出しエラーが発生するというような欠点があった。In conventional magnetic disk drives, vibration isolation for the base 5 has been achieved by using an elastic support 8 as shown in FIG. ) In a magnetic disk drive having a plurality of magnetic head positioning mechanisms (actuators) 4.15 g for the disks 2 mounted on the disk rotation shaft 14 of the book at regular intervals, one actuator 4 may move the other while reading information. When the actuator 15 operates, the reaction force is transmitted to the base 5, moving the disc 2 together with the base 5, and the actuator 4 that is being continuously moved cannot follow the movement, resulting in a read error. There was a drawback.

を提供することにある。An object of the present invention is to minimize the mutual vibration interference of a plurality of actuators 4.15 and the influence of external vibrations, especially regarding high-precision positioning of a magnetic head 3 and specific information on a disk 2 in a magnetic disk drive. Pressed anti-vibration restriction plate 1
Our goal is to provide the following.

構造を案出した。The base 5 is supported by an elastic support 8 in order to prevent vibration disturbances of the magnetic disk device and vibrations caused by the motor 6 and the like. However, since the elastic support body 8 has low rigidity, although the impact can be absorbed, the entire base 5 moves a large amount in the horizontal direction. Therefore, a structure was devised in which a vibration isolation limiting plate 1 is provided near the base 5 so that the base 5 does not move beyond a certain amplitude.
以下、本発明の一実施例を第２図によシ説明する。円板
２．磁気ヘッド３を駆動するアクチーエータ４，１５け
、ベース５に搭載されている。An embodiment of the present invention will be explained below with reference to FIG. Disc 2. Actuators 4 and 15 for driving the magnetic head 3 are mounted on the base 5.
ベース５は弾性支持体８により、きょう体７に固定され

振動を吸収してベース５に伝達しないような構造となっ
ている。防振制限板１は、ベース５の水平方向の振動を
一定振幅以下に押えろものである。The base 5 is fixed to the housing 7 by an elastic support 8, and the elastic support 8 has a structure that absorbs disturbance vibrations generated from the motor 6, etc., and does not transmit them to the base 5. The vibration isolation limiting plate 1 suppresses horizontal vibration of the base 5 to below a certain amplitude.

ラーを防止する。According to this embodiment, in a magnetic disk drive having a plurality of actuators 4 15 on the same base 5, during a read operation the magnetic head 3 of one actuator 4
Even if an operation is performed to drive the magnetic head 16 of the other actuator 15, and the base 5 supported by the elastic support 8 attempts to move in the horizontal direction due to the reaction force,
The movement of the base 5 exceeding a certain amplitude is restricted by the base 5 coming into contact with the vibration isolation limiting plate 1, and this action prevents a read error of the actuator 4 during a read operation.

に行なえるという効果がある。According to the present invention, by supporting the base 5 with the elastic support member 8, vibrations from outside the device can be prevented, and at the same time, by adding the vibration isolation limiting plate 1, the actuator 4, 15. Large movements caused by horizontal vibrations due to mutual interference can also be restricted, so information can be read out reliably.
