Abstract
Recording surface of an optical disk is segmented radially into a plurality of volumes each including a lead-in area, program area and lead-out area. In each of the volumes, information indicating presence of a succeeding volume is recorded in a main channel of the program or lead-out area. Dedicated player can receive the information indicating presence of a succeeding volume during reproduction of the first volume and thus is allowed to access the second volume. By contrast, non-dedicated or ordinary CD-ROM players have no capability to read the information indicating presence of a succeeding volume and thus is only allowed to reproduce the first volume without knowing the presence of the succeeding volume.
