Abstract: An information reproduction apparatus includes plural magazines in which optical discs are set, plural drives for performing recording and reproduction on an optical disc set therein, a changer mechanism that transports a magazine between its setting position and one or more drives and mounts and remove a prescribed optical disc or discs in and from the one or more drives by performing either one of a single move process and a multi-move process, and a controller. The controller judges whether to conduct the single move process or the multi-move process based on a reading data list and use statuses of the respective drives.

Abstract: An optical disc apparatus includes: a controller configured to acquire information of an access result and access positions on an optical disc when an optical disc drive unit configured to optically access an optical disc optically accesses the optical disc; and a storage configured to store the information acquired by the controller.

Abstract: A linear encoder includes a scale disposed within a housing and a scanning unit that is displaceable in a measuring direction relative to the scale. The scanning unit includes a scanning head disposed inside of the housing opposite to the scale such that the scale is scannable by the scanning head, as well as a mount to which the scanning head is fastened, and a driving component, via which the mount is coupled to a mounting base disposed outside of the housing. A vibration damper suppresses vibrations transversely to the measuring direction. The vibration damper is disposed on the mount or on the scanning head, and includes a damping mass and an elastic element. The damping mass is fastened by the elastic element to an attachment surface of the mount or of the scanning head.

Abstract: A conventional checking method—in which all of the optical disks are selected one by one from the plurality of optical disks stacked in a thickness direction and accommodated in a magazine—takes lots of time for checking. To solve the problem above, the optical disk device has a magazine, a disk drive, and a disk carrier device. The magazine accommodates a plurality of optical disks stacked in the thickness direction of the optical disks. The disk drive checks at least a recording surface facing an inner wall of the magazine of any optical disk of the optical disks accommodated in the magazine. Of the plurality of optical disks stacked and accommodated in the magazine, the disk carrier device takes out an optical disk positioned at an end in the thickness direction and whose recording surface faces the inner wall of the magazine, and carries it to the disk drive.

Abstract: The controller selects one command of the plurality of commands included in the command list. The controller selects one magazine that stores therein one recording medium designated by the one selected command, based on the magazine information, the controller moves the one selected magazine between the storing position of the one selected magazine and the plurality of recorder and player apparatuses using the carrier mechanism. The controller extracts all commands designating recording media stored in the one selected magazine, from the command list, based on the magazine information. The controller moves all the recording media designated by the extracted commands between the one selected magazine and the plurality of recorder and player apparatuses using the carrier mechanism.

Abstract: A process of reproducing information according to the present invention includes: reproducing record data recorded on an information-recording medium including a data area for recording the record data, and a defect control area for recording defect information of the data area; storing the defect information in a storage unit; and reducing a storage area of the storage unit which is used for storing the defect information.

Abstract: A recording apparatus which records information on a write once recording medium sequentially including a user data area, a first management information area, an indicator area and a second management information area on a recording layer thereof. The recording apparatus includes an optical head; and a control section for instructing the optical head to record information. The control section instructs to record management information in the first management information area; instructs to record indicator information indicating whether or not the management information has been recorded, in the indicator area; and instructs to record the same management information as recorded in the first management information area, in the second management information area.

Abstract: A recording apparatus and the like for creating an optical disc which is recognizable as a finalized disc even when an accidental power interruption or a serious write error occurs before finalize processing is completed is provided. The recording apparatus records information on a write once recording medium sequentially including a user data area, a first management information area, an indicator area and a second management information area on a recording layer thereof. The recording apparatus includes an optical head; and a control section for instructing the optical head to record information. The control section instructs to record management information in the first management information area; instructs to record indicator information indicating whether or not the management information has been recorded, in the indicator area; and instructs to record the same management information as recorded in the first management information area, in the second management information area.
