Abstract

PURPOSE: To simplify the rejection of adjacent crosstalk, with frequency interleave for the side band at carrier chroma signal band, recording the low band conversion carrier chroma signals in adjacent tracks through interleave, and enabling the high density recording.
CONSTITUTION: The color video signal is inputted to LPF2 and HPF3, and the luminance signal (a) and carrier chroma signal (b) are outputted at the output, FM modulation is made for the signal (a) with angular modulator 3, the output is fed to HPF4 to reduce the FM modulation wave present in the low band conversion carrier chroma signal band and it is fed to the mixer 5. On the other hand, the signal (b) is fed to the frequency converter 8, balance modulation is made with the carrier from the terminal 10, low conversion carrier chroma signal (d) is outputted via LPF9, it is fed to the mixer 5 via the phase selector 11, and it is fed to the video head 6 with mixing it with the signal (a). Further, in reproduction, FM luminance signal and low conversion carrier chrominance signal (e) are outputted with HPF12 and LPF13, the signal (e) is processed with te comb type filter 20, and it is mixed with the mixer 16 with the luminance signal demodulated at the FM modulator 14.
