Embodiment Construction

[0036] Before describing the embodiments of the present invention, problems in conventional devices will be briefly described. Since the data storage includes a plurality of disk drives, there is a tendency to increase the size of the device. In addition, the amount of recordable and reproducible data required by the data memory also tends to increase.

[0037] Therefore, a disk device capable of simultaneously performing recording and reproduction on both main surfaces of a single disk has been studied. Specifically, a disk device including a first optical pickup that performs recording and reproduction on the first surface of one disk, and a second optical pickup that performs recording and reproduction on the second surface of the same disk has been studied. According to this disc device, the amount of data that can be recorded and reproduced can be increased while suppressing the increase in size of the device.

[0038] However, in this disc device, since recording and r...

Abstract

This disc device includes: a first traverse chassis for holding a first optical pickup unit that records information to and plays back information from a first surface of a disc; a second traverse chassis for holding a second optical pickup unit that records information to and plays back information from a second surface of the disc; and first and second biasing members for biasing the first and second traverse chassis toward each other. The first and second traverse chassis are coupled to each other so as to rotate about a rotary shaft positioned at the back of a housing and extending along the width direction of the housing. At least either the first or the second biasing member is installed so as to incline relative to a conveyance direction, the thickness direction of the housing, and the width direction of the housing.

Description

technical field [0001] The present invention relates to a disk device capable of recording and / or reproducing information (hereinafter, abbreviated as recording and reproducing) on ​​optical discs such as DVD (digital versatile disk), BD (Blu-ray (registered trademark) disc), AD (Archival Disc) . Background technique [0002] Conventionally, disk devices having various structures are known (for example, refer to Patent Document 1). Conventional disk drives are generally configured so that recording and reproduction can be performed on one main surface of one disk. Hereinafter, such a disk device is also referred to as a "disk drive". [0003] In addition, in recent years, disk drives configured to include a plurality of disk drives and capable of simultaneously recording and reproducing a plurality of disks have become popular (for example, refer to Patent Document 2). Hereinafter, such a disk device is also referred to as a "data storage". [0004] prior art literature ...
