ABSTRACT:
The present invention discloses a disk player for recording information on a disk and/or reproducing recorded information thereon. The disk player includes a wobble detection unit for detecting a wobble signal corresponding to a wobbling pattern formed along a track of the disk; and an information processing unit for detecting a pre-pit signal recorded on the disk using the wobble signal output from the wobble detection unit and a clock signal obtained by multiplying the wobble signal a predetermined number of times, and for processing the information recorded on the disk or the information to be recorded thereon according to the detected pre-pit signal. Since the detection of a synchronization signal can be performed more precisely, this disk player can reduce error in the recording and reproduction of data.
