ABSTRACT:
A luminance signal Y and two color difference signals (R-Y), (B-Y) are separated from a color video signal. A color difference time division multiplex (TDM) signal is produced from the two color difference signals by a time base compression and time base multiplexing. A burst signal is added on the luminance signal and the color difference TDM signal as a time base information. The color difference TDM signal is recorded on an inner area of a disc. The luminance signal which has a wide signal band is recorded on an outer area of a disc which has a good frequency response characteristic. By separate recording of the two kinds of signals, a high resolution is obtained.
