ABSTRACT:
An information recording carrier according to one embodiment has minute pattern including plural grooves or lands formed to be substantially in parallel and adjacent each other and comprises a supporting body having the minute pattern, a recording layer formed on the minute pattern formed on the supporting layer and a light transmission layer formed on the recording layer. The minute pattern is formed under a relation of P<λ/NA, where a pitch of each groove or land is P, a wavelength of a laser beam is λ and a numerical aperture of an objective lens is NA. The plural grooves or lands have at least a wobbling region and data is recorded wobblingly in the wobbling region by frequency shift modulation. A phase relation between a high frequency portion and a low frequency portion composing the frequency shift modulation is ±(π/20.5) to ±(π/0.75).
