ABSTRACT:
An optical disk101includes a plurality of recording layers102and103and allows recording of information on each of the recording layers102and103. A spiral guide groove having wobbles meandering in radial directions of the optical disk101is formed on each of the recording layers102and103. Recording data can be recorded on or between the guide grooves. ADIP, which is address information embedded by wobble modulation of the guide groove, is recorded. The address information indicates positional information with respect to a radial direction of the recording layer102or103of the optical disk101on which the wobbles of the guide groove are formed.
