駆動機構の駆動。In a disk device, the present invention provides a drive mechanism that engages with an arm drive section to move the disk drive section in a direction opposite to the arm, a member that comes into pressure contact with the disk drive section and stops the disk drive section, and a drive mechanism that engages with an arm drive section to move the disk drive section in a direction opposite to the arm. A disk drive section operation switching mechanism is provided which separates the drive mechanism from the disk drive section when the member is pressed and engages the drive mechanism with the disk drive section when the member is detached, and a high-speed operation state in which a predetermined frame is searched at high speed using a big amplifier. At times, by moving the disk drive unit from the 1-arm drive unit via the drive mechanism, in other words, by moving the pickup and the disk individually to shorten the amount of movement in each part, wide-ranging high-speed access operations are possible. In addition, during low-speed operating states such as recording and reproducing operations, the disk drive section operation switching mechanism presses a member against the disk drive section to stop the disk drive section, and at the same time drives the drive mechanism.

移動量を短縮することによる大巾なアクセス動作高速化
を図っている。First, the general operation of this embodiment will be explained with reference to FIG. That is, the disk motor 4 of the disk drive unit 5
When performing a high-speed access operation in which a predetermined frame of the disk 1 rotating at high speed is searched at high speed, the drive motor 13 of the arm drive unit 10 is driven and the rotational force is applied to the pinion A.
This is done by moving the arm 7 and the pickup 8, which are integrated with the rack person 11, at high speed along the guide part 6 via the rack member 12.
The drive mechanism 20 is engaged with the arm drive section 10, and the disk drive section operation switching mechanism 30 transmits the driving force of the drive mechanism 20 to the disk drive section 5 as shown by the solid line in the figure to drive the disk. By moving the disk 1 in the opposite direction to the pickup 8, the amount of movement of the disk 1 and the pickup 8 is shortened, thereby greatly speeding up the access operation.

る。Furthermore, when in a low-speed operation state in which information is reproduced from the disc 1 or information is recorded on the disc 1, the disc drive unit operation switching mechanism 30 is in the connected state shown by the dotted lines in the figure, and the disc is driven by the pressure contact force of the member 40. stop section 5,
At the same time, since the driving force of the drive mechanism 20 is not transmitted to the disk drive section 5, only the pickup moves, and a predetermined low-speed operation can be ensured.
次に第２図も用いて本実施例の動作を詳細に説明する。Next, the operation of this embodiment will be explained in detail using FIG. 2 as well.

係合する。That is, in the high-speed access operation, the drive motor 13 of the arm drive section 10 is driven, the rack A11 provided on the arm 7 is operated via the pinion A12, and the arm 7 and the pickup 8 are moved at high speed along the guide section 6. However, in the present invention, the disk drive section 5 is also operated, that is,
A system control unit (not shown) operates the solenoid 34 that constitutes the disk drive operation switching mechanism 30, and moves the rotary lever 32 to the second position against the tension of the elastic body 33.
When it is rotated in the direction of arrow C in the figure, the member 40 provided at one end of the rotary lever 62 separates from the disk drive section 5, so that the disk drive section 5 can move along the guide section 6, and at the same time A pinion B22 in contact with the other end of the rotating lever 32 engages with a rack B21 provided in the disk drive section 5.

る。By the way, in this state, the pinion B of the drive mechanism 20
22 is engaged with the binion A12 that constitutes the arm drive section 10, that is, the binion B22 is engaged with the pinion A12.
12, the disk drive section 5 can move in the opposite direction to the arm 7 (a relationship in which the disk 1 moves in the direction B when the arm 7 and the pickup 8 move in the direction shown in the figure). Therefore, as a result, the arm drive section 10 moves the pickup 8 and the disk drive section 5 (disk 1) moves, respectively, and the amount of movement in each part is shortened, making it possible to perform a wide range of high-speed access operations. ◇ On the other hand, during low-speed operation such as reproducing information recorded on the disk 1, the solenoid 34 of the disk drive operation switching mechanism 30 does not operate at all, so the one-turn lever 32 is moved by the elastic body 33. The member 4o is rotated in the direction indicated by the arrow in FIG. 2 due to the tension, and the member 4o is pressed against the disk drive s5, and the pressure contact force causes the disk drive section 5 to stop and the pinion B22 of the drive mechanism 20 to be separated from the rack B21. (The state in which pinion B22 is indicated by a broken line in FIG. 2) Therefore,
The pinion B22 rotates because it is engaged with the pinion A12, but the rotational force is not transmitted to the disk drive section 5, and only the pickup 8 is moved along the guide section 6 at a predetermined operating speed. It can be moved.

A similar operation is also possible.

By moving the disk at the same time as the pickup movement through four mechanisms and shortening the amount of movement of each part, it is possible to perform a wide range of high-speed access operations.In addition, during low-speed operation, a disk drive operation switching mechanism allows parts to be switched to the disk drive. By applying pressure to stop the disk drive unit and then separating the drive mechanism from the disk drive unit, a predetermined operating speed can be ensured. This solves the problem of not being able to perform high-speed access operations, and when switching from high-speed operation to low-speed operation, the disk drive operation switching mechanism presses a member against the disk drive section, making it easy to control deceleration during high-speed access. High performance.
高信頼性のディスク装置を提供できる。A highly reliable disk device can be provided.
