Abstract

(57) [Summary] [Objective] To provide a disk device that can simultaneously drive a plurality of disks and provide high-speed access to required data. [Structure] A plurality of disks are rotationally driven by a plurality of rotary drive units, a pickup is configured to be movable across the plurality of rotation drive units, and a plurality of pickups can be concentrated on one disk.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to disk devices, and in particular to disk devices that can accommodate multiple disks at the same time. related to storage devices.

0002

[Conventional technology]

In conventional disc devices such as compact disc players, the data One pickup 15 is provided for the rotational drive means 14 that rotationally drives the disk 13. The disc 13 was played back by the pickup 15. Beep The pickup 15 is driven by a motor 16 and moves in the direction of arrow C to perform tracking. It was being done.

0003

[Problem that the idea aims to solve]

However, in conventional disk drives, one pickup is required for one disk. After accessing one piece of data, you can only pick the next piece of data. I had to move the backup and it took a long time to access the data. Or, if you have a recordable disc device, you can use the pickup to record. For important recordings that cannot be played back, the data recorded at the time of recording cannot be played back. Problems such as not being able to play back data and check whether it is recorded correctly There was a point.

0004 This invention was made in view of the above points, and it drives multiple disks at the same time. At the same time, we aim to provide disk devices that enable high-speed access to data. purpose.

[0005]

[Means to solve the problem]

This invention solves the above problem by rotating multiple disks separately. a plurality of rotary drive units provided in the a plurality of pickup sections for accessing a plurality of disks; At least one pickup section of the pickup sections is connected between the plurality of rotation drive sections. The configuration allows you to move the disk and access other disks.

[0006]

[Effect]

The plurality of disks are each rotationally driven by a plurality of rotational drive units, and the plurality of pickups are Recording or playback can be performed using the In addition, the pickup is connected between multiple rotary drive parts. Since the pickups can be moved, multiple pickups can be placed on one disc. Ru.

[0007] Therefore, data is played back alternately from one disc using multiple pickups. By doing this, it is also possible to access high-speed data. Also, one pick You can also play back with other pickups while recording with the pickup.

[0008]

【Example】

FIG. 1 shows a schematic diagram of an embodiment of the present invention. In the figure, 1 is the first disk, 2 indicates the second disk.

[0009] The first disk is placed on the turntable 3, and the second disk is placed on the turntable 3. placed on table 4. The turntable 3 is fixed to the rotating shaft of the spindle motor 5. As the spindle motor 5 rotates, the first disk 1 is rotated. Further, the turntable 4 is fixed to the rotating shaft of the spindle motor 6, and the turntable 4 is fixed to the rotating shaft of the spindle motor 6. The second disk 2 is rotated as the motor 6 rotates.

0010 7 is an optical pickup, which is connected to the motor 8, and as the motor 8 rotates, Move in the direction of arrow A. The motor 8 is fixed on a holding member 9. Holding member 9 is connected to a motor 10 and moves in the direction of arrow B as the motor 10 rotates. Ru. A configuration in which the optical pickup 7 also moves in the direction of arrow B as the holding member 9 moves. The configuration is such that recording/reproduction is possible on the first disk 1 and the second disk 2. ing.

[0011] 11 is an optical pickup, which is connected to the motor 12 and rotates as the motor 12 rotates. It is configured to move in the direction of arrow B. Optical pickup 7 is motor 8 to move the first disk 1 or the second disk 2 in the radial direction and perform tracking. will be carried out.

0012 The operation of the following device will be explained. First, the optical pickup 7 and the optical pick A case will be explained in which both the up 11 are for reproduction only. In this case, the first disk 1 and 2nd disc 2 can be played together, allowing high-speed random playback with 2 discs. Playback becomes possible. In addition, both the optical pickups 7 and 11 are used to select the first disk 1 or High speed random playback with one disc by playing the second disc 2 is also possible.

[0013] Next, the optical pickup 7 is used only for playback, and the optical pickup 11 is used for recording/playback. A case in which the pickup is configured will be explained. With this configuration Similarly, when the optical pickups 7 and 11 are both pickups for reproduction, High-speed random playback can be performed using two discs, and the first disc 1 or the Concentrate both optical pickups 7 and 11 on one of the two disks 2. While the optical pickup 11 is recording, the optical pickup 7 is recording. By playing back the recorded data, you can check the recorded data while recording. data can be recorded reliably. In addition, the optical pickup 7 The optical pickup 11 is used as a recording/playback pickup, and the optical pickup 11 is a playback-only pickup. A similar operation can be performed by configuring .

[0014] In addition, the optical pickups 7 and 11 may both be configured as recording/playback pickups. For example, recording can be performed on the first disk 1 and the second disk simultaneously, and one disk can be recorded simultaneously. High-speed random playback with one disc and high-speed random playback with two discs I can do life too.

[0015] Note that recording/playback was performed using two optical pickups, but this However, the method is not limited to this, and a plurality of disks are rotationally driven by a plurality of rotation drive means, A configuration may also be used in which recording/reproduction is performed using a plurality of optical pickups.

[0016] In addition, in this embodiment, the two optical pickups 7 and 11 are both movable, but one The configuration may be such that recording/reproduction is performed only on the disc.

[0017] In addition, although the embodiment describes an optical disk device, the invention is not limited to this. , or other disk-based media.

[0018]

[Effect of the idea]

As described above, according to the present invention, a plurality of pickups are connected to a plurality of rotational drive means. Since it can be moved in tandem, it is possible to operate multiple disks at once. It is also possible to concentrate multiple pickups on a single disk during recording. You can check recorded data on the fly and access data at high speed on a single disc. It has features such as being able to be accessed.
