Various optical discs such as a D-ROM are known.

As a disk drive for recording and / or reproducing information on and from these optical disks, there is a disk drive corresponding to a plurality of types of optical disks. For example, in addition to CDs and CD-ROMs, disk drive devices corresponding to CD-Rs and CD-RWs and DVDs have been proposed.

[0004] This type of disk drive device includes a loading mechanism having a disk tray on which various optical disks are placed, a disk rotation driving mechanism for rotating the optical disks, and recording of information corresponding to each optical disk. And / or an optical head mechanism for performing reproduction.

Description of the Related Art In a disk drive device, an optical disk placed on a disk tray is transferred to a mounting position in a device main body by a loading mechanism.

In the disk drive device, the optical disk transported to the mounting position is rotated by a disk rotation drive mechanism, and information is recorded and reproduced on the optical disk by an optical pickup of an optical head mechanism.

[0010]

By the way, the conventional disk drive corresponding to a plurality of types of optical disks described above has only one disk drive mechanism for driving the optical disks to rotate.

For this reason, the conventional disk drive device has a problem in that, while recording and / or reproduction of an optical disk is being performed, recording and / or reproduction of another optical disk cannot be performed at the same time. That is, the conventional disk drive device is, for example, a CD-ROM or a D-ROM.
At the time of reproduction of VD, etc., the reproduced information is
Or CD-RW etc. could not be recorded directly.

Therefore, when information recorded on an optical disk is recorded on another optical disk, desired information reproduced from the optical disk is temporarily recorded on a magnetic disk drive device, a so-called hard disk device. It was necessary to record on other optical discs such as CD-R and CD-RW. Therefore, recording work such as backup of information recorded on the optical disk is complicated and time-consuming.

In order to simultaneously reproduce information from an optical disk and directly record the reproduced information on another optical disk, a plurality of disk drive devices are required. In this case, there is a problem that two drive bays in which the disk drive device is incorporated are required.

For example, a personal computer generally has a thickness of about 41 mm, which is the height of the entire apparatus.
A drive bay for incorporating a so-called half-height type disk drive device is provided.

However, in a personal computer which has been reduced in size and thickness, generally, there are few cases where two empty drive bays for adding another disk drive device are secured in the device main body. It is often difficult to increase the number of drive devices.

When a so-called external disk drive is connected, there is a disadvantage that it is necessary to secure an installation space for a new disk drive.

Accordingly, the present invention provides a disk drive capable of simultaneously recording and / or reproducing a plurality of disk-shaped recording media and capable of reducing the size and thickness of the entire device. The purpose is to do.

A tray, first and second disk rotation drive mechanisms for rotating and driving the first and second optical disks, and first and second units for recording and / or reproducing information on the first and second optical disks. A second optical pickup, and an apparatus main body in which first and second disc trays are disposed at upper and lower stages, respectively. Further, this disk drive device includes a housing that covers the device main body. The outer shape of the housing is 40 m in height.
It is formed to have a width of 145 mm or more and 147 mm or less.

In the disk drive device configured as described above, the first optical disk mounted on the first disk tray is driven to rotate by the first disk rotation drive mechanism, and is driven by the first optical pickup. Recording and / or reproduction of information is performed. Further, the disk drive device has a second disk tray mounted on the second disk tray.
Is rotated by the second disk rotation drive mechanism, and information is recorded and / or reproduced by the second optical pickup. That is, this disk drive device independently records and / or reproduces information on the first and second optical disks. This disk drive device is suitable for a so-called half-height type drive bay because the outer shape of the housing is formed to have a height in the thickness direction of the entire device of 40 mm or more and 42 mm or less and a width of 145 mm or more and 147 mm or less.

04, the empty space in the height direction is effectively used, so that the height H of the entire apparatus can be reduced,
The entire device is reduced in thickness.

The above-described disk drive devices 101, 1
51 and 201 are arranged on the first and second disk trays such that the movement trajectories of the first and second optical pickups 41 and 42 are different from each other.
The space occupied by the first and second drive units 108, 109, 208, and 209 can be reduced in the thickness direction in the apparatus main bodies 104 and 204, so that the entire apparatus can be reduced in size and thickness. Can be planned.

Therefore, the disk drive 10
The first and second drive units 108, 109, 208, and 209 to which the first and second optical head mechanisms 23 and 24 are respectively assembled are reduced in thickness. Therefore, the device main bodies 104 and 20
A relatively large space can be secured for arranging a circuit board in the circuit board 4, and the restriction on the overall thickness of the circuit board on which various electronic components are provided can be relaxed. For this reason, the disk drive 10
According to 1,151,201, it is possible to use an inexpensive circuit board having a relatively large thickness, or to use an electronic component having a relatively large protrusion amount with respect to the main surface of the circuit board. By slightly increasing the thickness of the board, the area of the main surface of the circuit board can be reduced, and the manufacturing cost of the entire device can be reduced. Therefore, the disk drive devices 101 and 15
According to 1,201, the degree of freedom in designing the wiring pattern of the circuit board can be improved.

In the disk drive device according to the present invention, the relative positions of the first and second optical head mechanisms 23 and 24 are different on the projection plane parallel to the main surfaces of the first and second disk trays. With such a configuration, the first and second optical head mechanisms 23 and 24 may of course be arranged at other positions different from the above-mentioned disk drive device. Although the disk drive device according to the present invention is configured to include the first and second disk trays on which the first and second optical disks are mounted, for example, a disk having a magneto-optical disk It may be configured to include another disk tray on which the cartridge is placed.

[0077]

As described above, according to the disk drive device of the present invention, the size and thickness of the entire device are reduced, and information is recorded and / or reproduced on the first and second optical disks. be able to.
