摘要

PROBLEM TO BE SOLVED: To provide an information recording medium which is capable of performing stable tracking control, and which includes a data structure that facilitates access control to a prescribed position. SOLUTION: In the information recording medium (901) including a first recording layer (911) which allows information to be recorded/reproduced by an irradiation with a laser beam from a prescribed surface and a second recording layer (902) which is laminated for the first recording layer, the first recording layer includes a track on which information is recorded by phase change recording marks and a pit region (902) in which address information is recorded by embossed pits; and the second recording layer includes a track on which information is recorded by phase change recording marks and a pit region (902) in which address information is recorded by embossed pits, wherein the pit region of the second recording layer is laminated so as to overlap with the pit region of the first recording layer.
