Abstract
Apparatus permits the use of a known optical compact audio disc for providing a larger memory capacity so that data other than audio data can be reproduced therefrom while maintaining consistency with respect to signal format and signal processing, such as error correcting methods and recording data formats and the like, by providing write clock signals and read-out clock signals for reading into and out two memories the main digital data signal by using a subdigital data signal that is recorded on the disc along with the main digital data and which is reproduced from the disc at the same time as the main data in order to provide addressing of the main digital data on a more accurate level and with finer resolution, and a control system searches a playback location of the main digital data based upon the subdigital data as read out from the buffer memory, in which subdigital data has been written by the write clock signal.
