Abstract

PURPOSE: To prevent distortion of recording by controlling a rotating phase of a motor with a phase difference between the phase of a recording reference signal based on a vertical synchronizing signal in a recorded video signal and the phase of a reference signal based on a rotation detecting signal of a capstan motor.
CONSTITUTION: The recording reference signal at an input terminal 2 is inputted to a trapezoidal wave generating circuit 6 via a contact (b) of a switch 5, and a trapezoidal wave signal having a level rising for a prescribed period at a constant gradient from zero with the leading of the recording reference signal and reset to zero by the trailing of the reference signal is outputted from the circuit 6 to a comparator circuit 13. On the other hand, a rotation detecting signal FG of a capstan motor is inputted to an input terminal 3, subject to 1/4 frequency division 7 and outputted to a gate pulse generating circuit 12 via a switch 17. Then the circuit 12 generates a gate pulse at the leading of the reference signal, outputs it to the comparator circuit 13, and the circuit 13 outputs a phase control signal making the phase of the recording reference signal coincident with the rotating phase of the capstan motor to the capstan drive circuit.
