Abstract
A high speed data storage and retrieval system includes a storage module, a reader and a changer apparatus. Disc records enclosed in protective cartridges are transported between the reader and the storage module by the changer apparatus. The reader includes two mechanical systems--a system for receiving, securing and spinning a disc while it is enclosed in the cartridge and a pair of read heads which retrieve data stored on the surface of the disc. The storage module includes a plurality of storage locations for storing the discs. The changer apparatus comprises a carriage with a drive mechanism for driving the carriage to a desired position along the length of the storage module and at least two carriers for transporting discs with independent drive mechanisms. The carrier drive mechanisms drive the carriers in a direction normal to the direction which the carriage is driven. Simultaneous movement of the carriage and carriers permits high speed access of data.
