Optical disk library including optical disk media with non-standard thin hubs and disk drive spindle adaptor

摘要

Library apparatus for holding a plurality of disk cartridges wherein the library housing contains a slot for alignment with the entry slot of a disk drive. The cartridges are stacked upon an inner case within the housing and the case is driven vertically to align individual disk cartridges with the slot. A push/pull mechanism within the housing pushes the selected cartridge through the slot into the disk drive and pulls it back into the library when finished. A specially designed cartridge has a handle for interaction with the push/pull mechanism. A pseudo-spindle device is attached to the drive to enable the use of minimal-dimension cartridges in order to increase the number of disks that can be stacked within a given space in the library.
