Abstract:
1. A disk player, which records information on a disk and/or reproduces recorded information, comprising: a wobble detection unit for detecting a wobble signal corresponding to a wobbling pattern formed along a track of the disk; 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 output from the wobble detection unit, the clock signal obtained by multiplying the wobble signal a first 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; and a window generation unit for counting the clock signal in synchronization with an edge of the wobble signal and generating a window signal used by the information processing unit for detecting the pre-pit signal when the count of the clock signal reaches a predetermined count value.
