Abstract
An improved digital optical compact disc is disclosed which incorporates a further information storage element or area for storage and retrieval of track play selection information. The further storage area is comprised of defined information containing regions whose shading or alteration by the user indicates whether a corresponding track is to be skipped or played. An improved compact disc player reads the information containing defined regions and is capable of automatically selecting particular tracks for play. The information contained in the defined regions is stored in a format which is at-once visually-recognizable, machine-readable and manually-alterable.
