OPTISCHES INFORMATIONSAUFZEICHNUNGSMEDIUM, VERFAHREN ZUR HERSTELLUNG, UND VERFAHREN ZUR AUFZEICHNUNG UND WIEDERGABE

摘要

An optical information recording medium is provided with a plurality of information layers (2, 3), each of which has a sector structure in which a data area (8, 12) is divided in the circumferential direction by a sector address (9, 13). The positions of the sector addresses (9, 13) of the respective information layers (2, 3) coincide in the circumferential direction. This can prevent errors during reproduction caused by the effect of other information layers and stabilize recording characteristics, resulting in an increased recording capacity of a rewritable recording medium having a plurality of information layers with a sector structure.
