FIELD: information technologies.
SUBSTANCE: unitary record optical recording media, method of defect-management zone selection for the unitary record optical recording media and method of reserve zone selection of the unitary record optical recording media are announced. The method of defect-management on the unitary record optical recording media having, at least, one recording layer, includes selection steps, of at least, one defect-management zone having the fixed size, and, at least, one defect-management zone having the variable size. On the specified optical recording media the defect-management data recording, accordingly, is performed at least in one temporary defect-management zone having the fixed size, and, at least in one temporary defect-management zone having the variable size. Also one defect-management zone having the fixed size, and, at least, one defect-management zone having the variable size is used for record of the corresponding information.
EFFECT: improved method of recording.
