Abstract

PURPOSE: To reduce and eliminate the crosstalk given from the adjacent tracks by separating the color TV signal into the luminance signal and the chrominance signal and processing each signal component, and thus to secure the effective use of the limited band and then high-density recording.
CONSTITUTION: The luminance signal component is extracted through LPF2 from SECAM-system color TV signal 1 to be recorded, and then FM-modulated through FM modulator 3 to be applied to adder 5 via HPF4. At the same time, the FM chroma signal is isolated through BPF6 to be applied to balanced modulator 7. Then switch circuit 10 is switched according to the head switch signal to switch the output of oscillator 8 and 9 and then to be applied to modulator 7. And the chroma signal is applied to LPF12 in accordance with switch of the recording channels, and only the chroma component is applied to adder 5 via switch circuit 14. Then the chroma component is added to the FM luminance signal and applied to first channel head 16 and second channel head 16' to be then recorded on the recording medium
