Abstract

A cartridge which comprises an adapter cartridge and a caddy is employed for containing a hubless optical disk which can be processed in a standard optical disk drive for cartridges, such as an optical disk drive for an optical disk storage library. The adapter cartridge and the caddy are each provided with a recess so that when the adapter cartridge and the caddy are mated an enclosure is provided for the disk. The adapter cartridge carries a floating hub which engages a spindle in a drive for rotating the disk. The standard drive has a shutter arm which is employed for first ejecting the adapter cartridge from the drive and then is employed for ejecting the caddy and the disk from the adapter cartridge. This makes the caddy and disk readily accessible to a picker of a storage library for transport purposes or to an operator.
