A phase locked loop (PLL) control circuit for a digital audio disk system is disclosed which has a voltage-controlled oscillator (VCO) (116), a reference signal generator (106) for generating a reference signal corresponding to the phase state of a digital audio signal when the digital audio signal is reproduced or read out and which is recorded on a digital audio disk (DAD) (54) to have a maximum or minimum inverting period value predetermined by the eight to fourteen modulation (EFM) method, a phase comparator (110) connected to the output terminal of the reference signal generator (106) and the VCO (116), a detector (122) for detecting the maximum inverting period value included in the digital audio signal; and an adder (112) for adding outputs from the phase comparator (110) and the detector (122) and for supplying a sum result as an oscillation control signal to the VCO (116).
