Zusammenfassung:Disclosed is an information recording medium (1) having a plurality of pits (301) which are formed periodically, wherein information is recorded by irradiating a laser beam onto a pit string constituted by the plurality of pits (301) and changing the shape of the pits (301), the pit string is periodically wobbled, a length of a period (fp) of the pits (301) is a diffraction limit of the laser beam or less, and the period of the pit string is n times (n is a positive integer) of the period of the pits.
