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.
