Abstract

PURPOSE:To generate no dead part in a recording area, by recording the next track number to be recorded, in the front or the rear of an information block. CONSTITUTION:The surface of an optical disk 1 is constituted of an index recording area and a picture information recording area, an index formatting area 3 is provided on a part of the index recording area, and a picture information formatting area 4 is provided on a part of the picture information recording area. When recording, an optical head is moved to a preformatting area, a track number and information reproduced by the optical head are compared with the final track number which has been recorded, the optical head is moved by a track difference portion, and when this optical head has corresponded to the final recording track, its number is set to a counter so that its track number and information are recorded.
