Abstract

PURPOSE: To so arrange the apparatus that magnetic head accurately traces on magnetic tracks by having a means of generating index signal corresponding to vertical flyback time of each integer field.
CONSTITUTION: Compound video signal is supplied to terminal 401 at the recording and this compound video signal is supplied to a low-pass filter 404 and a synchronous separator circuit 402. The low-pass filter 404 which has the characteristics of a cut-off frequency 3MHz removes carrier color signal and high band part noises and supplies luminance signal to one end of an adder 1,405. The index signal (b) indicating the phase change of control signal S1 is applied to the other end of the adder 1,405. The luminance signal (a) having been applied with index signal (b) is applied to an FM modulator 406 and becomes an FM luminance signal. Rotating frequency controlling is accomplished by the generating signal of a frequency generator 1,416 and rotating phase controlling is accomplished by performing phase comparising of a reference signal and the generating signal of the frequency generator 1,416.
