Claims
- 1. A digital optical disc comprising:
- first and second sides and a center; and
- a plurality of defined regions containing information which is simultaneously both human and machine readable, said information being in a format which is manually alterable and located on the first side of the disc;
- at least one further defined region containing synchronization information, said further defined region located substantially at a same radial distance from a center of the disc as the plurality of defined regions;
- wherein said information is used to selectively access digitally encoded audio data stored on the disc.
- 2. The optical disc of claim 1, wherein said synchronization further defined region is in a format which is substantially not manually alterable.
- 3. A method of selecting a portion of audio information contained on a digital disc comprising the steps of:
- a) providing a digital optical disc comprising a plurality of defined regions containing information which is simultaneously both human and machine readable, said information being in a format which is manually alterable and located on a first side of the compact disc, wherein said disc further comprises at least one further defined region containing synchronization information;
- b) generating a first digital output representative of information contained in at least one of the plurality of defined regions by scanning the first side of the disc with a single scanner electrically connected to a disc player; and
- c) retrieving selected audio information from the disc based on the first digital output.
- 4. The method of selecting a portion of data contained on a digital disc of claim 3, wherein said synchronization defined region is located substantially at a same radial distance from a center of the disc as the plurality of defined regions.
- 5. The method of selecting a portion of data contained on a digital disc of claim 3, wherein the plurality of defined regions containing information are adjacent to one another and form a fist annular ring of spaced apart defined regions surrounding a center of the disc.
