Abstract: The PLL circuit in the disk drive, according to the present invention, is comprised of the following: a VCO (Voltage Controlled Oscillator) 11d, a frequency divider (DIV) 11e, a phase comparator (PC) 11a, a charge pump 11b, a low-pass filter (LPF) 11c, and a MIRR TE HOLD circuit 11f. Wherein, the LPF (Low-Pass Filter) 11c passes only low frequency components of the phase-error voltage, generated by the charge pump 11b, and provides the resulting, low frequency components passed, as a VCO control voltage, for the VCO. The phase comparator 11a compares the phase of a divided, VCO clock signal output from the frequency divider 11e, to that of an EFM signal. The divided, VCO clock signal results from the frequency-dividing of a VCO clock signal, which has been output from the VCO 11d, by the frequency divider 11e.
