摘要： A clock signal generating system of the present invention is provided for recording information on a disc. The disc has a plurality of recording tracks wobbled by a wobble signal having a predetermined frequency and a plurality of prepits disposed at positions having a predetermined phase relation with respect to a phase of the wobble signal. A clock signal is generated based on the wobble signal. A prepit signal is produced from the prepit. The phase of the wobble signal is compared with a phase of the prepit signal, thereby generating a phase adjusting signal. The phase of the clock signal is adjusted based on the phase adjusting signal. A recording clock signal for recording the information is produced by an adjusted clock signal.
