FIELD: optical data carriers.
SUBSTANCE: disk has area for recording data encoded in optical marks at certain recording density. Recording area has round or spiral recording tracks formed by servo-structure containing headers alternating with track portions. Headers contain information about location, encoded in preliminarily formed marks. Track portions contain periodical characteristics, for example, swaying, for synchronizing operation for reading and writing of data.
EFFECT: higher reliability.
