ABSTRACT:
A high speed data storage and retrieval system for use with disc record media includes a storage module for holding a plurality of discs, a read/write station and a changer apparatus for transporting discs between the storage module and the read/write station. In a preferred embodiment the storage discs are enclosed in a protective cartridge and held in place in the cartridge so that the recording surfaces of the disc do not touch the inside surfaces of the protective cartridge. The changer apparatus includes a pair of belt elevators. One of the elevators designated the "up" elevator transports a selected disc from the storage module to the read/write station. After processing, the selected disc is returned to the storage module via a second elevator which is designated the "down" elevator. A pivot block assembly is used to aid in the transfer of disc from the "up" elevator to the read/write station and from the read/write station to the "down" elevator. Additionally, the read/write station is provided with an ejector assembly for locating the cartridge and disengaging the disc inside of the cartridge and for ejecting the cartridge/disc assembly from the read/write station into the "down" elevator position. Further, the read/write station is provided with a parallelogrammatic spindle for insuring concentric location of the disc when mounted on the turntable.
