Optical information recording medium, method of manufacturing thereof, and method of recording and reproduction

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.
