Abstract
A technique for storing and retrieving information-containing discs using two independently operated disc transferring carriages is disclosed herein. The two carraiges are used to transfer discs between storage compartments forming part of an overall disc and drive library and one or more disc drives disposed within their own drive compartments also forming part of the disc and drive library. In one specific embodiment, the two carriages are moved vertically and horizontally on separate tracks between two confronting library arrangements.
