ABSTRACT:
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, includes 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.
