Abstract

PURPOSE:To exactly correct the variation in the time base of a color signal at the time of reproduction by controlling and frequency modulating the pedestal suiting part of the color signal so as to obtain a constant frequency and a phase. CONSTITUTION:A luminance signal from an input terminal 8 is transmitted to a changeover switch 62 through a clamping circuit 10, a switch 50, and an FM modulator 54. Color difference signals from input terminals 28, 30 are inputted to a memory module 44, through a clamping circuit 32, 34 and A/D converters 40, 42, and further transmitted to the switch 62 through the switch 50 and the frequency modulator 54. The frequency modulator 54 controls and modulates the pedestal-part of a color signal so as to obtain the constant frequency and phase. Thus frequency modurated luminance signal and color difference signals are supplied to magnetic heads 68a, 68b and recorded on a magnetic disk 70.
