A device for storing and retrieving cassettes includes a casing in which a plurality of cassettes are stored in a radial array about a vertically disposed axis. A carrier for transferring a selected cassette from the casing to a processor is pivotally mounted on the same axis as the casing for rotational movement about said axis. The carrier device is vertically moveable for alignment with different radial arrays of cassettes and the carrier is provided with a cassette gripper device which is horizontally moveable into said casing for gripping a selected cassette. The cassette gripping means is also mounted for rotational movement about a horizontal axis on the carrier device so that the cassette gripped thereby may be rotated to present one side or the other of a double sided disc within the cassette for processing.
