Abstract
A CD-ROM tower holds 100 CD-ROM disks or like media in five removable magazines. The magazines are identifiable by a robotics control system in the tower. The tower further includes four drives which receive the disks and transfer data from the disks to a SCSI bus. A transport mechanism controlled by the robotics control system raises and lowers an elevator with respect to the magazines and the drives. A tray picker mechanism on the elevator pulls a tray out of a magazine, and a disk lifter mechanism on the elevator lifts a disk from the tray. After the tray is returned to the magazine, the elevator is moved a drive and the disk is lowered onto the drive drawer. In similar manner, a disk is removed from a drive drawer and returned to a magazine tray. The tower is configured to use commercially available CD-ROM drives or other media drives so that the drives are available at commodity prices and are easily replaceable and upgradeable.
