  • Patent number: 5123000
    Abstract: An optical disk cartridge handling apparatus for storing, handling, reading and writing of optical disks contained in cartridges which store data for a host computer. The apparatus comprises an import/export element for loading and unloading cartridges into the apparatus. A cartridge store or library with slots therein stores the cartridges. The topmost slot initially receives the cartridges from the import/export element. A flipper mechanism is adapted to receive one of the cartridges from either the cartridge store or an optical disk drive. The flipper mechanism is adapted to invert or flip the cartridge and locate the cartridge adjacent the front of either the cartridge store or the optical disk drive. A picker mechanism moves the cartridge into and out of the flipper mechanism from either the cartridge store or the optical disk drive. Locating mechanisms are also provided for moving or locating the flipper and picker mechanisms.
