FIELD: optical information carriers.
SUBSTANCE: when data are overwritten on recordable and/or readable optical disk, method includes performing linking before physical cluster, from which overwriting process starts. In accordance to method, when overwriting is performed at portion of optical disk, on which information was recorded, or when overwriting is performed on portion including a defective area, linking is performed before portion, where overwriting is to be performed, or behind defective area, thus realizing reliable recording and reproduction of data. Invention makes it possible to perform reliable recording and reproduction of data by realization of linking in case when recording is performed after data, continuously recorded on high density optical disk, or in case, when overwriting is performed on high density optical disk with a defective area, and by recording a protective interval 3 at appropriate position, meaning end data of record.
EFFECT: increased efficiency.
