AbstractAn information handling system for use with information containing storage discs, specifically optical discs, is disclosed herein. This system, which may be referred to as a jukebox, includes a combination drive and disc storage unit, a separate disc storage unit without a drive, and a storage disc transport unit. The combination drive and disc storage unit contains a drive assembly for writing information onto and retrieving it from the storage discs as well as shelves for individually storing specific ones of the discs. The separate disc storage unit includes only the shelves. While the storage disc transport unit contains an arrangement of robotic components for transporting specific storage discs between their storage shelves and the drive assembly pursuant to commands from an external source, specifically from a control computer forming part of the system and an outside host computer.
