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: 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: 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.
