ABSTRACT:
The playback of a compact disc is enhanced by adhering to the compact disc an annular ring to increase the frictional engagement between the disc and the spindle upon which it turns. The playback is further enhanced by adhering a layer of soft, flexible material to dampen vibrations caused by the variations in speed by which the compact disc turns.
