摘要： In a recording/reproducing device for recording and reproducing an optical disk, when performing verify processing of inspecting a quality of recorded data and compare processing of inspecting whether the recorded data can be read without errors, a time is taken because the same area needs to be reproduced two times. The verify processing and the compare processing are performed at one time reproduction. To perform the verify processing and the compare processing simultaneously, a recording quality storage part is provided in the recording/reproducing device, and reproduced data is transmitted to a host controller while storing quality information at the time of reproduction by an instruction of the host controller. The host controller performs the compare processing by comparing transmitted data and data at the time of recording and inspects the recording quality by acquiring the quality information of a reproduced area from the recording/reproducing device at intervals set in advance.

摘要： A holographic memory apparatus includes an optical detector which receives reflected light of reference beam from the surface of a hologram recording medium. An incident angle of the reference beam is estimated on the basis of information on a focused position on the optical detector. When the incident angle is different from a target incident angle, the incident angle of the reference beam is adjusted according to a difference between the incident angle and the target incident angle.

摘要： A disadvantage is reduced in which a front panel of an optical disc unit tilts by a clearance (rattle) between the components and contacts with a body of a PC incorporating the unit to cause malfunction of insertion and ejection of discs. A disc tray is provided to move relative to rail guides attached to a bottom case of the optical disc unit via rails. The disc tray and rail guides have projection portions to contact with each other with stress. As a result, the clearance is reduced and the disadvantage due to the malfunction is reduced. The contact of the projection portions is close to point contact. The number of the contact positions is three or four. Support portions are provided to the rail guides to generate the stress.

摘要： Deduplication is executed in a storage device having low random access performance, such as an optical disk library. When an optical disk that is not inserted into an optical disk drive needs to be accessed in order to execute binary compare, data to be binary compared is stored in a temporary memory area in order to postpone the binary compare, and on the timing when the optical disk is inserted, the postponed binary compare is executed. Before second deduplication, which is deduplication between data to be stored in the storage device and the data in the optical disk library, is executed, first deduplication, which is deduplication between the data to be stored in the storage device and the data in the temporary memory area, is executed.
