FIG. 11 is a block diagram of a recording/reproducing system according to an embodiment of the present invention. - Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.
- An optical information storage medium generated by and/or usable with a recording/reproducing apparatus according to the present invention is a read-only optical information storage medium. The optical information storage medium is divided into a plurality of areas according to function or use purpose. A recording modulation method or a recording pattern used in a portion of the plurality of areas is different from a recording modulation method or a recording pattern used in the remaining portion of the plurality of areas.
- As described above, the optical information storage medium is divided into a plurality of areas according to function or use. For example, as shown in
FIG. 1 , the optical information storage medium includes aBCA 10, a lead-inarea 20, auser data area 30, and a lead-out area 40. Also, data is recorded as pits everywhere on the optical information storage medium. In other words, data is recorded as pits in theBCA 10, the lead-inarea 20, theuser data area 30, and the lead-out area 40. Thus, the read-only optical information storage medium is consistent with a recordable optical information storage medium in that data is recorded as groove wobbles everywhere on the recordable optical information storage medium. - Information on a serial number of the optical information storage medium or information indicating the
BCA 10 is recorded as pits in theBCA 10. Disc-related (or optical information storage medium-related) information, copy protection information, and so forth are recorded in the lead-inarea 20. For example, the disc-related information includes information on the type of a storage medium such as a recordable disc, write-one disc, or a read-only disc, information on the number of recording layers, information on the recording speed, and information on the size of the disc. - On an optical information storage medium generated by and/or usable with a recording/reproducing apparatus according to an embodiment of the present invention, patterns of pits formed in or recording modulation methods used in the
BCA 10, the lead-inarea 20, theuser data area 30, and the lead-out area 40 are different. - The different patterns of the pits formed in the
BCA 10, the lead-inarea 20, theuser data area 30, and the lead-out area 40 will be described. For example, the pattern of pits formed in theBCA 10 may be different from the patterns of pits formed in the lead-inarea 20, theuser data area 30, and the lead-out area 40. Here, the pattern of the pits formed in theBCA 10 may be a straight pit row or a pit wobble. A straight pit row has pits arranged in a straight row and a pit wobble has pits arranged in a waveform. - The pattern of the straight pit row and the pit wobble may be a single pattern, a specific pattern, or a random pattern. The single pattern refers to a pattern in which pits of length nT are arranged at regular intervals. Here, n denotes a natural number and T denotes the minimum pit length. For example, as shown in
FIG. 3A , the single pattern of the straight pit row refers to pits of the same length arranged in a straight row. As shown inFIG. 3B , the single pattern of the pit wobble refers to pits of the same length arranged in a waveform. - The specific pattern indicates that a sequence of pits of different lengths is repeated. For example, a sequence of pits of lengths 3 T and 6 T may be repeated. Here, a sync pattern may have pits of length 9 T. As shown in
FIG. 3C , the specific pattern of the straight pit row refers to specific pits arranged in a straight row. As shown inFIG. 3D , the specific pattern of the pit wobble refers to specific pits arranged in a waveform. - The random pattern refers to pits of different lengths arranged at irregular intervals. For example, as shown in
FIG. 3E , the random pattern of the straight pit row refers to pits of different lengths arranged in a straight row at random. As shown inFIG. 3F , the random pattern of the pit wobble refers to pits of different lengths arranged in a waveform at random. - Pits are formed in one of the single, specific, and random patterns of the straight pit row, and the single, specific, and random patterns of the pit wobble in the
BCA 10. Pits are formed in a different pattern from that used in theBCA 10 in the lead-inarea 20 and theuser data area 30. - In detail, as shown in
FIG. 4A , pits are formable in the single pattern of the straight pit rows in theBCA 10, and in the random pattern of the straight pit rows in the lead-inarea 20 and theuser data area 30. As shown inFIG. 4B , pits may be formed in the specific pattern of the straight pit rows in theBCA 10, and in the random pattern of the straight pit rows in the lead-inarea 20 and theuser data area 30. As another example, as shown inFIG. 4C , pits may be formed in the signal pattern of the straight pit rows in theBCA 10, and in the random pattern of the pit wobble in the lead-inarea 20 and theuser data area 30. In particular, in the case of the random pattern of the pit wobble, as shown inFIG. 4D , an amplitude of pit wobbles may gradually decrease or increase. - Here, a tracking servo for read-only data is generally performed according to a differential phase detect (DPD) method. The DPD method is known, and thus a detailed description thereof is omitted. If read-only data is recorded in the single pattern, a DPD signal is not detected. Thus, in this case, the DPD method cannot be used. However, in the present embodiment, information recorded in the BCA is read using only a focusing servo. Therefore, the DPD method does not affect the
BCA 10. In other words, as shown inFIGS. 4A, 4C , and 4D, although pits are formed in the single pattern in theBCA 10, it is not necessary to use the tracking servo. As a result, data is readable from the lead-inarea 20, theuser data area 30, and the lead-out area 40, but not theBCA 10, using the DPD method. - As another example, pits are formable in the random pattern of the straight pit row in the
BCA 10, and in the random pattern of the straight pit row or the random pattern of the pit wobble in the lead-inarea 20 and theuser data area 30. Alternatively, pits may be formed in the random pattern of the straight pit row in theBCA 10, and in the random pattern of the pit wobble in the lead-inarea 20 or theuser data area 30. Here, if pits are formed in the random pattern in theBCA 10, the pattern of the pits may be a “00h” pattern or a pattern containing information for representing theBCA 10. - Also, pits are formable in different pit patterns in the
BCA 10, the lead-inarea 20, and theuser data area 30. For example, as shown inFIG. 5A , pits are formable in the single pattern of the straight pit row in theBCA 10, in the random pattern of the straight pit row in the lead-inarea 20, and in the random pattern of the pit wobble in theuser data area 30. Alternatively, as shown inFIG. 5B , pits are formable in the specific pattern of the straight pit row in theBCA 10, in the random pattern of the pit wobble in the lead-inarea 20, and in the random pattern of the straight pit row in theuser data area 30. - Different recording modulation methods used in the
BCA 10, the lead-inarea 20, and theuser data area 30 will now be explained. - A recording modulation method used in the
BCA 10 is a RLL (d, k) modulation method or a bi-phase modulation method, and a different recording modulation method, is used in the lead-inarea 20, theuser data area 30, and the lead-inarea 40. - Bi-phase modulation refers to a method of displaying data depending on whether a signal varies within a predetermined period P. For example, as shown in
FIG. 6A , when the phase of a groove wobble does not change within a predetermined period P. a bit value “0” is read. When the phase of the groove wobble changes within the predetermined period P, a bit value “1” is read. In other words, the bi-phase modulation method is a method of recording data depending on whether a signal varies within a given period, e.g., depending on whether the phase of a signal changes within a given period. Here, modulation of the phase of a groove wobble has been described, but various patterns may be modulated. - As shown in
FIG. 6B , if a pit does not change within a given period P, a bit of value “0”(or “1”) is read, and if the pit changes within the given period P, a bit of value “1” (or “0”) is read. In other words, if a pit is formed everywhere within the given period P, a bit of value “0” (or “1”) is read, and if a pit and a space are formed within the given period P; a bit of value “1” (or “0”) is read. - The RLL modulation method indicates how many bits of value “0” exist between two bits of value “1”. Here, RLL (d, k) indicates that the minimum number and the maximum number of bits of value “0” between two bits of value “1” are d and k, respectively. For example, in a RLL (1, 7) modulation method, the minimum number and the maximum number of bits of value “0” between two bits of value “1” are 1 and 7, respectively. According to the RLL (1, 7) modulation method, when d=1, data of “1010101” is recorded and thus a mark of length 2 T is formed between two bits of value “1”. Also, when d=7, data of “10000000100000001” is recorded and thus a mark of length 8 T is formed between two bits of value “1”. Here, T denotes the minimum mark length, i.e., the minimum pit length. Thus, in the RLL (1, 7) modulation method, data is recorded as marks and spaces of length 2 T to 8 T.
- As described in the above example, the recording modulation method used in the
BCA 10 is different from the recording modulation methods used in the lead-inarea 20, theuser data area 30, and the lead-out area 40. Alternatively, the recording modulation method used in the lead-inarea 20 may be different from the recording modulation methods used in theBCA 10, theuser data area 30, and the lead-out area 40. For example, the recording modulation method used in the lead-inarea 20 may be the RLL (d, k) modulation method or the bi-phase method, and the recording modulation method used in theBCA 10, theuser data area 30, and the lead-out area 40 may be different from the recording modulation method used in the lead-inarea 20. - A track pitch of the pits formed in the
BCA 10 may be equal to or different from a track pitch of the pits formed in the lead-inarea 20 and/or theuser data area 30. - An optical information storage medium generated by and/or usable with a recording/reproducing apparatus according to another embodiment of the present invention is divided into a plurality of areas according to function or use. A pit pattern or a recording modulation method used in a portion of the plurality of areas is different from pit patterns or recording modulation methods used in the remaining portion of the plurality of areas.
- For example, the lead-in
area 20 may be divided into a plurality of sub-areas. In other words, as shown inFIG. 7 , when the lead-inarea 20 is divided into afirst area 20 a and asecond area 20 b, pits may be formed in different pit patterns or according to different modulation methods in thefirst area 20 a and thesecond area 20 b. Pits are formed in the single, specific, or random pattern of the straight pit rows, or the single, specific, or random pattern of the pit wobbles in thefirst area 20 a. Pits are formed in a pattern different from that in thefirst area 20 a, in thesecond area 20 b. - For example, as shown in
FIG. 8A , pits are formable in the random pattern of the straight pit rows in thefirst area 20 a, and in the random pattern of the pit wobbles in thesecond area 20 b. Alternatively, as shown inFIG. 8B , pits are formable in the specific pattern of the straight pit rows in thefirst area 20 a, and in the random pattern of the straight pit rows in thesecond area 20 b. - Furthermore, the pit pattern used in the
first area 20 a or thesecond area 20 b may be different from the pit patterns used in theBCA 10 and theuser data area 30. For example, as shown inFIG. 9A , pits are formed in the single pattern of the straight pit rows in theBCA 10, in the specific pattern of the straight pit rows in thefirst area 20 a, and in the random pattern of the straight pit rows in thesecond area 20 b and theuser data area 30. As shown inFIG. 9B , pits are formable in the single pattern of the straight pit rows in theBCA 10, in the random pattern of the straight pit rows in thefirst area 20 a, in the specific pattern of the straight pit rows in thesecond area 20 b, and in the random pattern of the pit wobbles in theuser data area 30. - As another example, the
user data area 30 is dividable into two or more sub-areas. Pits may be formed in different pit patterns in the sub-areas, or the pit patterns used in the sub-areas may be different from a pit pattern used in theBCA 10 or the lead-inarea 20. Also, different recording modulation methods are usable in the sub-areas, or the recording modulation methods used in the sub-areas may be different from a recording modulation method used in theBCA 10 or the lead-inarea 20. - Meanwhile, when data is recorded in the user data area 30 (shown in
FIG. 7 ), as shown inFIG. 10 , the data is recorded in each ofbasic recording units 33. Run-ins 31 and run-outs 35 are located before and after thebasic recording units 33. Here, thebasic recording units 33 may be physical clusters, sectors, ECC blocks, frames, or the like. The run-ins 31 and the run-outs 35 are for accurately recording and/or reproducing data in thebasic recording units 33. In other words, if data is recorded in the run-ins 31 or the run-outs 35 in slightly the wrong position, the run-ins 31 and the run-outs 35 corrects the error so that data is effectively recorded and/or reproduced. - Pits are formable in the run-
ins 31 and the run-outs 35 in the same pit pattern as that used in theuser data area 30. For example, when pits are formed in the random pattern of the straight pit row or the random pattern of the pit wobble in theuser data area 30, pits are also formed in the random pattern of the straight pit row or the random pattern of the pit wobble in the run-ins 31 and the run-outs 35. As an example of the random pattern, “00h” is recordable. As shown inFIG. 10 , pits may be recorded as “00h” in the run-ins 31, thebasic recording units 33, and the run-outs 35. - In the meantime, pits may be formed in the run-
ins 31 and the run-outs 35 in a different pit pattern from theuser data area 30. - Data is recordable in a portion of at least one of a plurality of areas of an optical information storage medium using a different recording modulation method from the remaining areas of the optical storage medium.
- For example, data is recordable in the
first area 20 a according to the RLL (d, k) modulation method and in thesecond area 20 b according to the bi-phase modulation method. Alternatively, data is recordable in thefirst area 20 a according to the bi-phase modulation method, and in thesecond area 20 b, theBCA 10, and theuser data area 30 according to the RLL (d, k) modulation method. In contrast, data is recordable in thefirst area 20 a according to the RLL (d, k) modulation method, and in thesecond area 20 b, theBCA 10, and theuser data area 30 according to the bi-phase modulation method. - Referring to
FIG. 2 , there is shown a schematic view of recording/reading unit which records to and reads from an optical storage medium such as, by way of non-limiting examples, a CD or a DVD. - The recording/reading unit includes a
light source 1 for recording and reproducing information onto and from optical storage medium D. The recording/reading unit also includes aflat beam splitter 2 is arranged on a path of the beam emitted from thelight source 1, a reflectingmirror 3 for directing beams which are emitted from thelight source 1 and then reflected from theflat beam splitter 2 toward the optical storage medium D, and acollimator lens 4 for shaping the beams reflected from themirror 3. - The recording/reading unit further includes an
objective lens 5 for spotting the beams shaped by thecollimator lens 4 onto the optical storage medium D, and aphotodiode 6 for detecting recorded information and an error from the beams reflected from the optical storage medium. - Referring to
FIG. 11 , there is shown a block diagram of a recording/reproducing system according to an embodiment of the present invention. The apparatus includes recording/reading unit 100 which may be the recording/reading unit ofFIG. 2 and a controller 200. The recording/reading unit 100 writes data to and/or reproduces data from a write once recording medium 300 that is an information storage medium. - The present invention is applicable to an optical information storage medium having two or more recording layers as well as to an optical information storage medium having a single recording layer. In other words, the present invention is applicable to each recording layer of a multi-layer optical information storage medium.
- As described above, an optical information storage medium generated by and/or usable with a recording/reproducing apparatus according to the described embodiments ensures compatibility with a drive by prescribing a pit pattern or a recording modulation method used in a BCA, not in a data area. As a result, data reproduction efficiency can be improved and the optical information storage medium can be used conveniently. In addition, the optical information storage medium can maintain consistency with the format of a recordable optical information storage medium.
- Although a few embodiments of the present invention have been shown and described, the present invention is not limited to the above-described embodiments. Instead, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
