A compact disc handler includes a picker elevator containing a helically threaded lead screw journaled for rotation about a vertical axis and having a traveling nut thereon to which a disc picker arm is attached. A guideway in the tower cooperates with the picker arm to constrain the picker arm from rotating until reaching a predetermined height elevator. Using this design, a CD can be retrieved from an input hopper, placed in a label printer or other CD publishing/playing device and upon completion of same operation on the disc, it is transported by rotation to an output hopper.
