Abstract
PURPOSE:To minimize the bit error rate even when the recording modulation system with different recording density is used by controlling the clock frequency of a clock recovery circuit minimizing the it error rate of a demodulated data. CONSTITUTION:A frequency of a reference signal of a voltage controlled oscillation circuit 13 and a time constant of a low pass filter circuit 14 are controlled so as to minimize the bit error rate included in the demodulated data DT to obtain a recovered clock signal CK10 in a clock recovery circuit 11. Thus, the clock of the clock recovery circuit 11 is controlled variably as a whole to obtain a recovered clock signal CK10 to minimize the bit error rate and the recovered clock signal corresponding to the recording modulation system with different recording density is obtained.
