An information recording carrier in one mode has minute pattern including plural grooves or lands formed in parallel and adjacent each other and comprises a supporting body having the minute pattern, a recording layer formed on the minute pattern, and a light transmission layer formed on the recording layer. The minute pattern is formed under a relation of p<.lamda./NA, where a pitch of each groove or land is P, a wavelength of a laser beam is .lamda. and a numerical aperture of an objective lens is NA. The plural grooves or lands have at least a wobbling region where data is recorded wobblingly by frequency shift modulation. A phase relation between the high and the low frequency portion composing the frequency shift modulation is .+-.(.pi./2.5) and the high and the low frequency portion are continuous in phase at a border between the high and the low frequency portion.
