摘要：
A method for recording broad-band color video signals in which the broad-band 3-color signals are separated into narrow-band 3-color signals and a high-band monochrome signal having a higher frequency band. The high-band monochrome signal is divided into three bands and frequency-converted respectively. The frequency-converted three bands of the high-band monochrome signal are merged into the narrow-band 3-color signals, while maintaining the frequency interlace relationship, so that three composite color video signals are produced. The thus produced three composite color video signals are recorded on different regions of recording medium.
