ABSTRACT:
A clock signal generating system using a wobble signal and a data reproducing apparatus, has a first block to detect a frequency error signal or a phase error signal from the RF signals on the recording medium and to output the detected frequency error signal or the detected phase error signal. A second block detects a wobble error signal from the wobble signals on the recording medium and outputs the detected wobble error signal. A clock generating unit generates a clock signal using the detected frequency error signal or the detected phase error signal of the second block when the RF signals have an error, and using the detected wobble error signal of the first block when the wobble signals have an error.
