Abstract
A system for interfacing an optical disk autochanger having a robot and a plurality of disk drives to a host includes a master SCSI bus, a subordinate SCSI bus, a SCSI multiplexer and a move controller. The master SCSI bus is connected to the host. The subordinate SCSI bus is connected to the plurality of disk drives. The multiplexer is connected between the master SCSI bus and the subordinate SCSI bus. The multiplexer transfers communications between the host and a selected disk drive. The move controller receives jukebox control commands from the host and selects the disk drive based on the jukebox control commands.
