A technique for storing and retrieving information containing discs utilizing a movable disc storage magazine is disclosed herein. The disc storage magazine, which is designed to store a plurality of information containing discs in individual compartments, is movable along a predetermined path which passes through a specific disc storage station such that each of the individual compartments is positionable within that station. At the same time, a disc drive for storing information on and retrieving information from the discs is located at a disc drive station spaced from the disc storage station. Means are provided for moving the disc storage magazine in a way which places a desired magazine compartment at the disc storage station and means are provided for transferring an information containing disc between that compartment and the disc drive station. |

DETAILED DESCRIPTION What is claimed is: 1.
An apparatus for storing and retrieving information containing discs, comprising: (a) a disc storage magazine for storing a plurality of said information containing discs in individual compartments, said magazine being movable along a predetermined path including a specific disc storage station such that each of said individual compartments is positionable within said disc storage station; (b) means for moving said magazine along said predetermined path; (c) means including a disc drive for storing information on and retrieving information from said discs, said disc drive being located at a disc drive station spaced from said disc storage station; (d) means for transferring an information containing disc between said drive at said disc drive station and one of said magazine compartments when the latter is at said disc storage station, said transferring means including (i) a transfer arm mounted for rotation about an axis perpendicular to the transfer arm and through its center such that the ends of said arm move along a common circular transfer path through both said storage station and said drive station, (ii) carriage means located at each end of said transfer arm for retrieving an information containing disc at either one of said storage or drive stations and for delivering it to the other station by rotating said transfer arm in a controlled way, and (iii) means for rotating said transfer arm in said controlled way so as to cause said carriage means at each end of the arm to move along said circular transfer path between said storage and transfer stations; and (e) means for controlling the movement of said magazine along its predetermined path and for controlling said transferring means for transferring specific information containing discs between said magazine and drive.
2.
An apparatus according to claim 1 wherein said transferring means is configured to transfer a disc from the magazine compartment at said storage station to said drive while simultaneously transferring a disc from said drive to said last-mentioned compartment
