The present invention relates to an optical disk, an optical disk device, and an optical disk recording method. When it is applied to, for example, a compact disk. It attempts to reduce a jitter at the time of reproduction, and reproduce surely the recorded data. A change pattern of a modulation signal (S2) is detected, and the timing of a modulation signal (S1) is corrected according to this change pattern, to irradiate a laser beam L.
