Abstract
Apparatus permits the use of a compact audio disc to provide digital data information other than audio signals without requiring a change of format of the audio disc and involving only minor changes to existing digital audio disc playback apparatus. Data signals are rearranged to permit searching of the data information in a fashion compatible with existing digital audio disc playback apparatus and maintaining consistency with respect to signal format and signal processing, such as error correcting and recording data format presently used in compact digital audio discs.
