FIELD: optical data carriers.
SUBSTANCE: data carrier has data area. The latter has multiple zones, in which code blocks with error corrections are formed and sectors remaining as a result of sliding replacement at the end of zone, number of which is less than necessary for forming of one code block with error corrections. Said sectors are not used for recording one code block with error corrections and are skipped, and said code block with error corrections is formed at the beginning of next zone after skipping sectors of zone noted above. Carrier has additional free space, necessary for skipping sectors remaining at the end of zone during sliding replacement process.
EFFECT: higher efficiency.
