Abstract
PURPOSE:To stabilize the operation of a phase synchronization loop even when the regenerative speed of a motor is variable by cooperating frequency varying means of a reference frequency signal and frequency responding range varying means of a phase synchronization loop. CONSTITUTION:The oscillation output of an oscillator 1 is divided in frequency by a frequency divider, and is inputted to a phase comparator 3. A synchronization signal read by a pickup 5 and detected by a synchronization signal detector 6 is inputted from a disc 4 to the other input of the comparator 3. The erroneous output from the comparator 3 is applied through a low pass filter 7 to a voltage controlled oscillator 8, thereby controlling the oscillating frequency of the oscillator 8. The oscillating frequency of the oscillator 8 is converted via a frequency/voltage conveter 9 to a voltage providing the driving voltage of a motor 10. A potentiometer 1a for varying the frequency of a reference frequency signal for varying the reproducing speed and a variable capacitor 8a of the oscillator 8 are interlocked.
