したことを特徴とするカラー信号記録再生回路。[Claims for Utility Model Registration] During recording, an FM modulated luminance signal derived from a recording luminance signal processing circuit after frequency converting a color signal separated from a recording color video signal and converting it into a low frequency converted color signal. When playing back, the low-frequency converted color signal is frequency-converted and converted back into a high-frequency color signal, and then the F
In the color signal recording and reproducing circuit that mixes the M demodulated luminance signal and derives the color video signal for reproduction, the color video signal for recording is passed through the reproduction bandpass filter that removes the converted carrier component from the converted color signal during reproduction. The color signal is inputted and separated into color signals, and a phase compensation circuit is disposed in the recording luminance signal processing circuit to eliminate the time lag between the low frequency conversion color signal and the FM modulated luminance signal during mixing. Signal recording and reproducing circuit.
