この発明は磁気ディスク装置の円板間およびアーム間の
温度差の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the temperature difference between disks and arms of a magnetic disk drive.

れている。Conventionally, there has been an actuator for a magnetic disk drive as shown in FIG. In the figure, (1) is a coil bobbin, 12+[a coil wound on this coil bobbin (1), +31. -C71 is the arm fixed to the coil bobbin (11, C8) is the arm +3L-' +71 has one or several pieces each fixed to the head C. In the diagram, l is drawn only in (3), +91 is the arm 31,-
(The shaft is fixed to 71 and is usually supported by bearings at the top and bottom.
コイル（２）の周囲には永久磁石が存在する（図では省

ッド（８）の位置が正確に決定さノア、る。Next, the T111 work will be explained. When the coil (2) is energized, the fill (2) receives force from the magnetic field of the surrounding permanent magnets and moves around the shaft (9). As a result, the arm (31-" The shaft (9) is also the axis. Based on this position information, the entire head (8) is stopped at an appropriate position, and the positions of the other heads (8) are accurately determined.
従来のアクチェータは以上のように構成されているので
、コイルからの熱／バ直接アームを加熱しソノタめコイ
ルに近いアームはど温度が上昇してその結果アームやそ
の近傍にある記録用円板の線膨張量に差を生じて２円板
への記録密度が高い場合にはヘッド＋８）の正確な位置
決めができない欠点があった。Conventional actuators are constructed as described above, so the heat from the coil directly heats the arm, causing the temperature of the arm near the coil to rise, resulting in a drop in the arm and the recording disk near it. If the recording density on the two discs is high due to a difference in the amount of linear expansion, there is a drawback that accurate positioning of the head +8) cannot be performed.
この発明は、上記のような従来のものの欠点を除去する

置を提供することを目的とする。This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by installing a heat shielding means between the coil and the arm, a plurality of arms arranged in the direction of the axis (9) and It is an object of the present invention to provide a magnetic disk device having an actuator that allows high-density recording by reducing the temperature difference between disks to a minimum.

For the sake of clarity, a part of the arm is shown as a cross-section, but (
This is a heat shield plate that is located between the coil and the arm and is fixed to the arm, and is made of a material with good heat insulation properties. The shield plate must be installed so that it does not touch the coil.
