Abstract
A method and apparatus for recording a color video signal on a recording medium such as video disk in which effects of crosstalk between adjacent recorded tracks are eliminated and the level and phase of the subcarrier signal are maintained constant. The video signal to be recorded is processed so that the phase of the subcarrier signal is constant from frame to frame of the video signal. The video signal thus processed is recorded utilizing an FM modulation system. Specifically, the video signal is separated into a luminance signal and a subcarrier signal. Subcarrier signals to be recorded on adjacent recording tracks are superposed on the luminance signal after processing of the video signal.
