Abstract

A compact-disk player for playing a compact disk that carries data in a plurality of program blocks recorded on the disk. The program blocks are dividable into sections by indices which are stored for each program block. Each index has starting and ending times that are also stored. Any index within any program block may be selected, and an optical scanner scans the compact disk to be played. The amount to be skipped by the optical scanner to arrive at a position that corresponds to the selected index, is calculated from the stored starting and ending times.
