ABSTRACT:
An optical disk recording device, an optical disk playback device, and an optical disk system have a large on-line capacity, a high speed data transfer speed, and a smooth data transfer speed. The optical disk recording device includes a plurality of recording units to record on a plurality of optical disks and a control unit that divides the data to be recorded between a plurality of optical disks, sends the divided data to the plurality of recording units, and fixes the amount of data recorded per unit time on each disk. In the optical disk playback device, a plurality of playback units replaces the plurality of recording units. The control unit controls, as substantially fixed, the total playback amount of data per unit time from the plurality of optical disks, and combines data from the plurality of optical disks played back by the playback units. In the optical system, the device accepts a magazine of optical disk cartridges that each house an optical disk. The optical disks are loaded into a plurality of recording or playback units by a conveying unit, with the conveying unit including multiple conveyance devices.
