ABSTRACT:
An optical disk library apparatus equipped with a function of automatically cleaning an optical head in a drive unit. This optical disk library apparatus comprises a cartridge entry/eject mechanism for entering an optical disk cartridge into the library apparatus and ejecting the optical disk cartridge from the library apparatus. Also included is a cell unit having a plurality of cells each for holding the optical disk cartridge therein, a drive unit having an optical head to record data on and/or to reproduce the same from the optical disk cartridge, and outputting a head cleaning request signal on the basis of information relative to soil of the optical head, and an accessor for carrying the optical disk cartridge among the cartridge entry/eject mechanism, the cell unit and the drive unit. The optical disk library apparatus further includes an accessor control means for controlling the accessor to carry a cleaning cartridge from the cell unit to the drive unit in response to a head cleaning request signal obtained from the drive unit. When a cleaning request signal is outputted, the optical head is automatically cleaned by the use of the cleaning cartridge carried by the accessor.
