摘要： An information recording medium is provided with a wobbled track, wherein at least a part of the track is subjected to wobbling based on a wobble signal in which at least a part of recording information is randomized. Each track is wobbled at a randomized frequency, so that a frequency of a wobbling signal obtained from the wobbled track is randomized. As a result, the influence of crosstalk between adjacent track is reduced.
