Abstract

A suck-in optical disk loading system, which is compatible with various disks having different sizes, comprises an upper cover (600), a bottom case (616), and an inner transferring unit (609) with compatible jaws (702). A case comprising an inner transferring unit (609) is constructed by fixing the upper cover (600) to the bottom case (616) tightly. For the height difference exists between the upper cover (600) and the sidewall of the bottom case (616), a groove-liked track (618) is formed on the inner surface of the sidewall of the case. The track (618) is used for guiding the inner transferring unit (609). The inner transferring unit (609) has a set of compatible jaws (702), which are used for judging the size of an optical disk inserted and clamping the optical disk tightly during its movement. After the inserted optical disk is arrived at the final reading and writing position, a lever mechanism is used for warding off a insert slot (807), in order to prevent from inserting another optical disk during the reading and writing period of the disk witch has been inserted.

Description

Inhalation type optical disc loading system compatible with large and small discs

The present invention relates to an optical disc loading system for recording information using optical discs (e.g., information storage media such as CDs and DVDs). More particularly, the present invention relates to a slot-loading optical disc loading system having a compatible device. Background technique

Due to the high performance of optical discs and the characteristics of all-digital storage, optical discs have become the main data storage medium and have become more and more popular in people's lives. In an existing disc loading system with a disc compatible and drive device, a suction and discharge disc loading system is mainly used in a car disc playback system. This slot-loading disc loading system contains a signal switch and a snap ring.

When the user inserts the disc into the disc slot, the disc will touch the tab inside the jack and adjust the size of the disc according to the size of the inserted disc. The adjustment of the snap ring is accomplished by squeezing the spring inside the snap ring with different sized discs. Thereby, the compatibility of the disc loading system is achieved.

After insertion, the disc first triggers the signal loading in the system and causes the motor to start. The motor loads the disc into the disc reading player and places it in the correct position for reading and writing. Although the laser head of such a disc loading system can be fixed at a fixed point and ensure normal reading of data, this type of disc loading system has a complicated structure. In particular, the transmission mechanism includes many components. Because of the high precision of production, the production cost is high.

Another disadvantage of such an optical disc loading system is that the spring of the snap ring is compressed according to the size of the inserted disc. The disc is held up by the left and right directions. In order to be able to clamp an 80 mm optical disk, when the 120 mm optical disk is lifted, the optical disk is subjected to a large pressure from the snap ring, and as a result, the optical disk may be deformed, destroyed, or badly read and written.

Another existing optical disc loading system with compatibility and drive is a disc loading system with different levels of concentric structure. The disc is loaded into the appropriate location by the disc cartridge. This type of disc loading system has a simple structure. However, since more than one disc cartridge is to be used, and a certain gap is required between the disc and the disc cartridge to ensure smooth rotation of the disc after the disc is loaded into the disc loading system, the disc drive device must have Quite thickness.

In addition, in order to lift the disc to form a gap with the disc cartridge, it is necessary to design a movable connection between the fixing member and the laser head member, such as between the spindle motor and the objective lens. As a result, it is very difficult to avoid shocks, and it is difficult to avoid the impact of directly reading the correctness of the data reading of the optical disc. What's more, after long-term use, this problem is even more serious when the parts are aged or even malfunctioning. The noise of the disc loading system can become very large. 98 SUMMARY OF THE INVENTION

Accordingly, the present invention is directed to a slot-loading optical disc loading system that is compatible with optical discs of various sizes. The new slot-loading disc loading system uses a number of disc controls to determine the various dimensions of the disc after insertion of the disc, and thereafter transfers the disc to the final designated location for data reading and writing by different transfer operations.

SUMMARY OF THE INVENTION The main object of the present invention is to provide a compatible slot-loading system which is relatively simple in construction, low in manufacturing precision, relatively low in manufacturing cost, does not distort the damaged disc, and has a good gripping effect. The housing of the compatible slot-loading system includes a socket, a pair of clips, a compatible device, and an inner slide. Disc control is also utilized to determine the inserted disc. Once the size of the inserted disc is determined by the disc control, the transfer operation corresponding to the disc size is determined and activated.

Compatible devices are used to determine the size of each inserted disc and to determine the transfer operations that need to be made. During the transfer of the disc, the disc is clamped tightly to the inner slider. A wall groove is formed in the vertical wall of the housing so that the inner slider operates together with the guide bar to ensure that the inserted optical disc is smoothly fed into the final designated position for high quality data reading and writing.

The inner slide operates with the guide to ensure that the inserted disc is smoothly fed into the final designated position. The transfer operation also requires the use of meshing racks, worm turbines and motors. In addition, a limiter is provided on the inner slide to prevent the inner slide from separating from the meshing rack.

Inside the housing, bumps are placed at appropriate locations on the bottom of the loading system. Separate bumps are provided on the compatible device and the clip. At the final designated position, the split lugs will be lifted by the bumps and separate the disc from the inner slide.

A capping device similar to the shape of a hat is used in the present invention. The upper raised portion of the hat-like shape can be embedded in the hole opened in the top cover of the casing. At the beginning of the transfer operation, the platen device is placed above the inner slide and is confined above the turntable of the disc because the cap-like raised portion is embedded in the hole. During the transfer operation, the platen device is first stationary above the inner slide and then moved over the inserted disc. When the disc reaches the final designated position, the clip opens and releases the disc. The disc and the platen device above it will fall onto the turntable of the laser head. The platen unit presses the disc tightly. High quality data reading and writing can be done.

A second object of the present invention is to further simplify the structure of the loading system to further reduce product cost. To achieve this goal, the new slot-loading system reduces the number of parts required to accommodate a wide range of discs and improves grip during operation.

The housing of the compatible slot-loading system is now composed of a top cover and a bottom box that is tightly coupled to the top cover. A socket for the disc to enter and exit is at the front end of the housing. The compatible device and clip are designed as an assembly to determine the size of the disc and to clamp the inserted disc tightly onto the inner slide. Therefore, you only need to use a set of magnetic blocks and iron pieces instead of the previous two sets of magnetic blocks and The iron piece prevents the compatible clip from coming off. The inner slide is placed inside the housing for chucking the disc to the read and write position.

Two sets of disc controls replace the original three disc controls to determine the size of the disc. The first set of controls is a series of discs for judging small discs and the second set of controls is for judging large discs. This first group is in parallel with the second group of controls.

A number of guide posts are provided on the side of the inner slide to ensure a smooth transfer of the disc. In particular, the inner surface of the side wall of the housing is provided with a groove-shaped track instead of the previous wall groove. When the top cover is closed with the bottom case, a housing having an inner slide inside is formed. The inner slider is inserted into the groove track of the inner wall of the casing with a certain number of guide posts, and moves along the rail from the vicinity of the front end socket of the casing toward the rear end of the casing.

The shape of the track has also been improved. The descending bevel formed at the end of the track allows the disc to be separated from the inner slide and also allows the disc to be removed after the laser head is read or written. At the end of the descending ramp, there is a short track that is parallel to the groove track. That is, the track is made into a "Z" shape. This parallel short track at the end of the descending bevel gives a certain initial power during the take-up operation, making the take-out operation easier.

At the final position of the disc, the bumps are used to lift the separation block to separate the inserted disc from the inner slider. The lower pressing block below the inner slide presses the lever that leans against the side of the lug such that a flap at the rear end of the socket is lifted and blocks the socket to prevent reinsertion of the disc.

This newly developed and improved model significantly reduces the manufacturing cost and manufacturing process of the slot-loading system. This compatible slot-loading system eliminates the need for wall slots on the side walls and separate clips to accommodate compatible devices. Therefore, the volume of the loading system is greatly reduced and the efficiency is improved. Most importantly, using two sets of disc controls to determine the size of the inserted disc is a good design that is both easy to use and prevents possible judgment errors. In particular, they can be easily modified to accommodate the size of different discs in the future. DRAWINGS

Optical discs have become the main information storage medium in the digital age. The present invention has made a breakthrough in the transmission mechanism of the optical disc loading system and the compatibility of different size optical discs. The optical disc loading system designed by the present invention is capable of solving all of the shortcomings of the current loading system. A number of specific embodiments of the invention are set forth herein.

Specific examples of the two previously filed patents, WO2004/077427 and WO2005/031733 are incorporated herein by reference. As shown in FIG. 1, a specific embodiment discloses a housing 100, an inner slider 122, a set of clips 119, a compatible device 117, and a disc clamp 101. The housing 100 includes position adjustment controls 124, 127 for position adjustment, and a worm gear 113 is used in conjunction with the motor 114 to drive the inner slide 122. The inner slider has a disc accommodating groove 110 for holding the optical disc. When the inserted disc reaches the final designated position, the function of the positioning control 124 is similar to the stop switch for controlling the operation of the motor. Similarly, when the inserted optical disc is sent out, the function of the positioning control 127 is equivalent to a stop switch for controlling the operation of the motor. The disc turntable 116 is part of a laser head with a stand that is mounted at the bottom of the housing 100. After the disc enters the final position to be read and written, the disc turntable 116 is used to hold the disc. A bump 112 is provided at the bottom of the housing. The socket 115 has vertical walls 123, 125 on both sides, and a wall groove 126 is formed in the vertical wall 123. Fig. 2 shows another embodiment, and a further description of the wall groove provided on the vertical wall of the housing is provided. The structure of the housing is slightly different from the housing structure shown in Figure 1. As can be seen in Fig. 2, the optical disk socket 201 for accessing and exiting the optical disk has a standing wall 200 on both sides. Two sets of wall grooves 203 are provided on the standing wall 200. In Figure 2, two guides 205 are used with the inner slides to allow the disc to be transported to the correct read and write position. The meshing rack 204 is used in conjunction with the motor to transfer the optical disc inserted from the jack to the final designated position for reading and writing. When the disc reaches the final designated position, the disc holder 202 above the disc is dropped onto the disc carousel together with the disc, and the disc is pressed to ensure high quality data reading and writing.

Further, as shown in Fig. 3, an adjustment control is provided at an appropriate position at the bottom of the housing 100 to adjust the relative position between the inner slider 122 and the housing 100. The position control 300 is comprised of a bracket 306 and two springs 301 that are secured to the bracket 306 by adjustable screws 302, 305. Two circuit connectors 303 and two shrapnels 301 are used to connect into one circuit.

More specifically, Figure 1 shows a specific embodiment of an optical disc loading system. The compatible device 117 is above the clip 119 and the clip 119 is above the inner slide 122. The compatible device 117 includes a second split bump 118, a second iron piece 102, and a set of curved retaining rings 104. A small disc control 103 is on the inside surface of an arcuate retaining ring 104 with two guiding ramps 105 at the front end of the two arcuate retaining rings 104.

When a small disc is inserted, the mini disc control 103 will be touched first. The transfer operation of the small disc will be activated. If a large disc is inserted, the disc is too large to enter the arcuate retaining ring 104. As a result, a large disk 105 will be touching the guide slope and thus the retaining ring 104 from the top arcuate under-compliant device 117 to enter, it will touch and the second and third disc transfer operation control and activation of a large disk ₀

The embodiment embodiment clip 119 shown in Figure 1 is provided with a third split tab 120 and a first magnet block 106. The inner slide 122 shown in Fig. 1 includes second and third 121 disc controls. A first iron piece 109 and a second magnetic block 108 are also provided. The second iron piece 102 is attracted by the second magnetic block through the aperture formed at the corresponding position on the clip 119. The compatible device 117 and the clip 119 are thus closely attached together. The curved retaining ring rests on the disc receiving groove 110. In the middle of the disc accommodating groove 110, there is a slit 111 which expands a rectangle which extends in a circular shape to the inner slider 122 and which allows the laser head to be exposed and read and write.

Also, the compatible device 117 is enlarged in Fig. 4 for a clearer display. The compatible device 400 is provided with a pair of curved retaining rings 402 and a matching beveled surface 401. A set of curved retaining rings 402 has an arc less than or equal to a half arc. The middle portion of the compatible device has a rectangular opening. This cornice is larger than the inner slide 122 and conforms to the rectangular slit 111 thereon for free access to the laser head and ensures high quality data read and write operations.

Referring to Figure 5, a small disc control 103, the second 107 and the third 121 disc control basic A schematic diagram of the structural connection 500. The second 107 and third 121 disc controls are first connected in series to each other and then to the mini disc control 103 in parallel. These disc controls have a simple and consistent structure, for example, two sheets of conductive metal 501, either brass or bronze, forming an electrical circuit inside the plastic shell 502.

When the small disc is inserted, the small disc control 103 provided on the compatible device 117 can judge and activate the transfer operation for the small disc. When the large disk is inserted, the second 107 and third 121 optical disk controls provided in the inner slider 122 can judge and activate the transfer operation for the large disk. Once these controllers determine the size of the inserted disc, the transfer operation will also be determined and activated accordingly.

In the embodiment of Figs. 1 and 2, the portion of the inner disk member 122 where the disk receiving groove 110 is in contact with the optical disk is affixed with a fleece to prevent damage to the disk when the disk is chucked. The front end of the inner slider 122 is also provided with a rubber layer that prevents abrasion of the disc. The rear end of the clip 119 and the compatible device 117 is coupled to the rear end of the inner slider 122, and the front end is freely flipped within a certain angle. The first iron piece 109 is attracted by the first magnetic block 106 during the transport of the optical disk to tightly clamp the optical disk. Through the attraction between the two sets of magnetic blocks and the iron sheets, the compatible device 117, the clip 119 and the inner slide 122 are closely attached to each other.

The sockets 115 of the housing 100 are adjacent to the vertical walls 123, 126 on both sides. The upright walls 123, 126 are provided with a number of wall slots 126 which are used to transport the disc. The guides that are inserted transversely between the walls 123, 126 ensure that the disc is smoothly transferred to the final proper position for high quality read and write operations. The meshing rack 204 and the motor are also employed by the transfer operation.

A stop means, such as a projection extending in the direction of the meshing rack 204, is disposed on the inner slider 122 to prevent the inner slider 122 from being disengaged from the meshing rack 204. A bump 112 is provided at a suitable position in the housing 100 at the bottom of the loading system. In addition, the second separating protrusion 118 is disposed on the compatible device 117, and the third separating protrusion 120 is disposed on the clip 119. When the inner slider 122 is moved to the vicinity of the final designated position of the optical disk, the bump 112 lifts the separation projection to separate the clamped optical disk from the inner slider 122.

The present invention further develops and improves the inhalation type optical disc loading system. A specific embodiment is shown in Figure 6. Referring to Figure 6, the particular embodiment shown includes a rectangular upper cover 600 with stepped sidewalls 604, an inner slide 609 with a compatible clip, and a bottom case 616 with a worm worm 615, convex Block 617 and a motor 614. The upper cover 600 and the bottom case 616 are fastened together to form a housing for the loading system. The upper tab 603 and the lower tab 612 are screwed. These tabs 603, 612 can be further screwed and secured to other system components to create a computer, CD player, or other CD recording system.

The upper cover 600 has a hole 601 which functions as a restriction means for allowing the insertion of the cap-like projection of the disk holder 608 into the hole. The restriction aperture 601 has a downwardly short loop that limits the disc clamp 608 from resting over the disc turntable 621 of the laser head and stays on the disc clamp tray above the inner slide 609 in the idle state. When an optical disc is inserted, the inner slider 609 starts to Move away from the rear of the socket. At the same time, the inserted disc slowly replaces the inner slider 609 and becomes below the disc holder 608. After the inner slider reaches the final point, the optical disc is released by the inner slider 609. The disc holder 608 will fall onto the disc turntable of the laser head together with the inserted disc and press the disc tightly against the disc turntable 621.

On the stepped side wall 604 of the upper cover 600, an opening 602 is left for the power plug 611 of the external device of the housing to be connected thereto. Since the height of the stepped side wall of the upper cover 600 is greater than the height of the side wall 613 of the bottom case 616, a groove-like track 618 is formed on the inner surface of the side wall 604 of the loading system after the housing is formed. The height of the track 618 is equal to The difference in height between the side wall of the upper cover 600 and the side wall 613 of the bottom case 616. Specifically, the relatively long and relatively wide side walls of the upper cover 600 will be fastened and encased by the side walls 613 of the shorter and narrower bottom case 616. A recess is formed on the side wall 613 of the bottom case 616 and the stepped area of the upper cover 600. Some curing lugs 624 are provided on the bottom side wall 613 to further enhance the secureness of the bottom case 616. A concave block 605 formed on the outer surface of the stepped side wall 604 forms a convex surface on the inner surface of the stepped side wall 604. This concave surface 605 is designed to maintain the uniformity of the thickness of the upper cover 600.

Two pairs of guide projections are provided on the side wall of the inner slider 609. A pair of guide projections 606 at the front end are larger than the guide projections 607 at the rear end. The laser head having the frame 619 is fitted to the bottom of the bottom case 616 with some anti-vibration screws 622. The disc turntable 621 is located near the front end dust shield 625 of the bottom case 616. A bump 617 having an angled bevel 620 is provided adjacent the worm gear 615 to lift the separation tab below the inner slide 609. A stop switch 623 is mounted on the rear wall of the bottom case 616. When the inner slider 609 reaches the final position, that is, the rear wall of the bottom case, the inner slider 609 will open the stop switch 623 and stop the transfer operation. Of course, the laser head can also be mounted in another way and read and write data on top of the disc.

An inner slide 609 provided with a compatible clip 702 can be described in more detail by means of Figure 7. Two clips 702 are secured to the top of the inner slide 609. Two magnets 705 are embedded in the apertures in the front end of the compatible clip 702 near the socket. On the underside of the compatible clip, the magnet 705 can be permeable and attracted by the iron piece 706 located on the upper surface of the inner slide 609. Two separate projections 707 are disposed on the bottom surface of the clip 702. When the inner slider 609 is moved, the iron piece 706 and the magnet 705 attract each other and tightly clamp the inserted disc. The intermediate position of the inner slider 609 has a relatively circular portion and a rectangular slot 704 for the laser head to move. A disc accommodating groove 708 with respect to the maximum disc size is formed at the front end of the inner slider 609 to hold the disc. The disc cartridge tray 703 disposed at the intermediate position of the inner slider is slightly higher than the disc tray 708, and the disc cartridge 608 is parked therein when it is in an idle state.

The rack 712 is mounted below the inner slide 609 for transfer operation. On the underside of the compatible clip 702, two small disc controls 710 are mounted adjacent the edges of the slot 704, respectively. These small disc controls 710 are connected in series to determine the size of the inserted disc. If only one control is installed, the large disc can also touch and activate the controller due to unbalanced insertion. Therefore, adopt A pair of disc controls.

The split lug 707 is mounted on the outer edge of the compatible clip 702 for separating the inner slider 609 and the transported disc when the inner slider 609 transports the disc to the final designated position. The slope 720 at the top of the separation bump 707 corresponds to the slope angle of the slope 620 on the bump 617. In addition, a pair of curved retaining rings 718 with guiding ramps 719 are mounted at the foremost end of the compatible clip 702. The curved retaining ring 718 functions like a disc receiving slot for holding a small disc inserted into the loading system.

However, when a large disc enters the loading system, the disc first touches the leading ramp 719 at the top end of the compatible clip 702. Once the guide ramp 719 is touched by the large disc, the compatible clip 702 will be lifted. The large disc slides under the compatible clip 702 and rests on the disc receiving slot 708 of the inner slider 609. Above the inner slider 609, the disc receiving groove 708 is slightly lower than the disc holder tray 703. The disc receiving slot 708 is equivalent to a receiving slot and a limiting device.

Figure 8 further illustrates the construction of inner slide 609 and compatible clip 702. The compatible clip 702 is secured to the inner slider 609 by a hinge device 802. This compatible clip 702 can be opened and closed in the interior space of the housing. The magnetic block 705 and the corresponding iron piece 706 are used to provide the role of the disk clamp. A set of large disc control 801 is mounted on the upper surface of the inner slider 609, and is used to judge the size of the large disc when the large disc is inserted. A set of holes 804 is provided corresponding to the limit device 803. The position limiting device 803 is for preventing the optical disk from being excessively forced into the inner slider 609 and touching the large disk control 801.

When a small disc is inserted, the small disc control 710 at the front end of the compatible clip 702 is first touched. The curved retaining ring 718 of the compatible clip 702 will hold the small disc and initiate the transfer operation of the compact disc. In other words, the curved stop 718 will also limit the small disc from staying on a portion of the disc tray 708. After the small disc reaches the final designated position, the bump 617 lifts the split tab 707 to open the compatible clip 702 and release the small disc from the inner slider. The disc holder 608 will fall with the small disc and tightly hold the disc on the disc turntable 621. Data read and write operations begin. The present invention uses a set of small disc controls to prevent erroneous activation due to unbalanced insertion of large discs.

When a large disc is inserted, the diameter of the disc is too large to touch the compact disc control 710. Instead, the large disc will actuate the guide ramp 719 mounted on the curved end retainer 718 of the compatible clip 702 and hold the compatible clip 702. The inserted disc enters between the inner slider 609 and the compatible clip 702. The large disc is then further inserted and reaches the large disc control 801 located near the inner edge of the rectangular slot 704. Then, the large disc transfer operation is activated.

Figure 8 shows a top view of the loading system. A disc insertion slot 807 activates the inner slider 609 to move. Guides 606, 607 are disposed on both sides of the inner slider 609. The guides 606, 607 are inserted into the track 618 formed by the top cover 600 snapping the bottom case 616. When the inner slider 609 is moved toward the rear end of the loading system, the short guide protrusion 607 can pass through the stop point 605 formed by the groove of the outer surface of the upper cover 600. However, the long guide 606 cannot pass the stop point 605. When the short guide 607 reaches the orbit At the end of 618, the bump 617 on the bottom case 616 contacts and lifts the split tab 707, and thereby the compatible clip 702 will open and release the inner disc. Subsequently, the inner slider 609 slides down the slope of the end of the rail 618 and descends to a position lower than the disc turntable 621.

At the same time, referring to FIG. 9, the lower pressing block 906 under the inner slider 609 presses one of the lever end 902 of the lever to lower it, and forces the other lever of the lever located near the socket 807 to rise, thereby lifting up The flap 903 blocks the socket 807. Figure 9 shows two cross-sectional views of a particular embodiment of the invention. The lever assembly is provided with a fulcrum shaft 901, with one shank end 902 leaning against the lug 617 and the other shank extending to a flap 903 below the socket 807. When the lower clamp 906 depresses the lever lever 902, the flap 903 rises and blocks the socket 807 from reinserting the disc.

FIG. 9 shows a cross-sectional view of a track 618 formed on the inner surface of the stepped sidewall 604. In the idle state, the inner slider 609 is stationary near the upper front end socket 807 of the loading system. A support device 900 is disposed on the side wall of the bottom case 616 for supporting the inner slide member 609. When the inner slider 609 has just begun to move along the track 618, the short guide 607 passes through the stop point 605, and the support device 900 supports the inner slider 609 to prevent it from sliding into the first slope 904. The inner slide 609 will continue to move.

At the end of the transfer process, the long guide 606 will be stuck by the stop point 605 because the support device 900 has not provided any support under the inner slide 609. Therefore, the short guide 607 of the inner slider 609 will slide down the ramp 907 and rest in the flat section 908. At the same time, on the other side, the long guide 606 of the inner slide 609 will slide down the ramp 904 and rest in the flat section 905. The ramp 904 and the flat section 905 are parallel to the ramp 907 and the flat section 908, respectively. The inner slide 609 is finally parked at the lower rear end of the loading system. In addition, the initial transfer action at the flat sections 905, 908 can produce an inertia such that the inner slide 609 can more easily climb the ramp to remove the disc during the unloading process.

Referring now to Figure 10, a cross-sectional view of the loading system and a top view of the bottom case 616 are shown. The support device 900 and its relative position to the inner slide 609 are primarily shown in cross-section. Moreover, the top view of the bottom case 616 shows the position of the support device 900 on a side wall and its relative position to other components. The lever device 1000 and the support device 900 are mounted on one side of the bottom case 616, while the worm gear 615 and the motor 614 are on the other side. The laser head 619 and the bracket will be placed in an appropriate position 619 at the bottom of the bottom box 616.

Figure 11 shows a top view of the upper cover 600, the inner slide 609 with the compatible clip 702, and the bottom case 616. The bottom box 616 shows all of the major components of the loading system of the present invention. Parallel bevels 904, 907 on track 618 are better illustrated in the top view of FIG. The ring 1101 surrounding the limit hole 601 is also clearly depicted in the figure. The rack 712 is on one side of the inner slider and the lower block 906 is on the other side. In particular, the specially designed drive gear 1102 on the bottom case 616 is clearly shown in the drawings. Further cross-sectional views in Fig. 12 depict the relative positions of the main components within the loading system, such as inner slide 616 and lever mechanism 1201, as well as inner slide 616 and drive unit 1202.

The pinning process of the entire optical disc is further described in FIGS. 13 to 16. In Figure 13, the exhibition The inner slider 609 in the idle state is compatible with the clip 702, the disc turntable 621, and the disc clip 608 is stopped on the disc clip tray 703. In the idle state, the intermediate convex portion 1301 of the disc carousel 621 can be clearly seen when the structure of the loading system is viewed from the front of the socket 807 inserted into the optical disc.

When the optical disk 1401 has just been inserted, the inner slider 609 is in the vicinity of the front end socket 807 as shown in FIG. The inner slide 609 then grips the disc tightly and moves in the direction in which the disc is inserted. The disc cartridge 608 is transferred from being parked on the disc cartridge tray 703 to be parked on the inserted optical disc 1401 and finally stopped on the inserted optical disc 1401. Upon reaching the final designated position, since the compatible clip 702 is lifted by the separation tab 707, the inserted optical disk 1401 is separated from the disk clamp 608 and the inner slider 609 thereon. The inner slider 609 is lowered, and the inserted optical disc 1401 and the disc holder 608 are dropped onto the disc reel 621 as shown in FIG. The intermediate raised portion 1301 of the disc turntable 621 is inserted into the hole in the center of the disc so that the disc turntable chucks the disc to rotate. This is also the case where the intermediate convex portion 1301 is not seen in Fig. 15. In this position, the disc turntable 621 is slightly higher than the position of the inner slider 609.

Figure 16 shows the detachment of the disc during the unloading operation. When the unloading operation is initially started, the compatible clip 702 will slowly close and the inner slider 609 will ramp up and rise slightly to the inserted disc 1401 that can be clamped in the read and write position. The inserted disc 1401 is lifted and the disc turntable 621 remains stationary; therefore, the intermediate raised portion 1301 appears again in Fig. 16.

Thus, based on the operations set forth above, the constructed laser head frame is closely related to the efficiency and operation of the present invention. The height of the inner slide 609, the height of the disc turntable 621, and the height of the compatible clip 702 need to be carefully calculated to ensure that the disc can be smoothly conveyed. The present invention also utilizes specially manufactured anti-vibration screws to ensure high quality data read and write operations.

Although the present invention has been described in terms of specific embodiments, many modifications and descriptive applications will be apparent to those skilled in the art. Therefore, it is to be understood that the invention may be practiced otherwise than as specifically described herein. Therefore, the description of the more suitable settings in the present invention should be considered in all respects as illustrative and not limiting.
