ABSTRACT:
A storage and retrieval system for a plurality of data storage media includes a 3-dimensional data storage media storage cabinet having a plurality of moveable data storage media storage locations, at least one of which is empty or unused. Each data storage media storage location is moveable along at least two orthogonal axes, to facilitate retrieval of a selected one data storage media. Each data storage media is indexed in a data storage media system controller. When access to a predetermined one data storage media is requested by a command or request from a data processing system such as a host computer, the data storage media system controller, utilizing the index, determines the media transport control signals required to effectuate the quickest access to the media. A retrieval mechanism retrieves the media from a retrieval region in the storage cabinet and places the media into and out of a read/write mechanism, to allow access to the data storage media. The storage cabinet is preferably arranged in a number of rows, each row including at least one empty storage location, to allow movement or shuffling of the data storage media within each row.
