Patent ID: 7859961

Claim:
An optical disk recording method for recording predetermined data on an optical disk on the basis of a first reference clock signal used for recording, the optical disk including a groove track having a wobble signal recorded thereon and a land track having a land pre-pit carrying track position information, the first reference clock signal being generated on the basis of the wobble signal reproduced from the optical disk, the method comprising the steps of: reproducing a pre-pit signal from the optical disk; generating a second reference clock signal from the pre-pit signal; detecting an amount of phase shift of the first reference clock signal using the second reference clock signal; and correcting the first reference clock signal on the basis of an average value of the detected amount of phase shift, wherein, a first phase control signal or a second phase control signal is selected based upon a phase-control-signal-selection signal such that: if the first phase control signal is selected, then the first reference clock signal is generated, and if the second phase control signal is selected, then the second reference clock signal is generated.
