Abstract

PURPOSE:To eliminate the variance of the phase for the synchronous oscillation output and also simplify the overall constitution of the recording/reproducing circuit, by using the oscillating circuit which synchronizes with the burst signal during the recording for the voltage control oscillating circuit and at the same time using the 1st phase detecting circuit to eliminate the burst amplifying circuit. CONSTITUTION:The 1st, 2nd and 4th switching circuits 47, 49 and 55 are switched toward the input terminal R each during the recording. And the 3rd switching circuit 51 is turned on, and the signal supplied through the recording standard color signal input terminal 41 is supplied to one input terminal of the 1st phase detecting circuit 50, as well as to one input terminal of the 1st frequency converting circuit 48. On the other hand, the 2nd phase detecting circuit 54 oscillates the 2nd voltage control oscillating circuit 56 in synchronization with the video synchronous signal fH. As a result, the recording color signal is led to the output terminal 42. Then each switch is inverted during the reperoduction. And the reproducing low-range converting color signal f1+4f1 is supplied to one input terminal of the circuit 48. Thus the reproduced color signal of the standard color frequency f0 is led out through the output terminal 46.
