Abstract

PURPOSE:To ensure the recording of the steady color picture by performing the alternate recording so that the horizontal synchronous signal recording positions may be adjacent on the adjacent recording tracks. CONSTITUTION:The video signal is separated into the luminance and chrominance signals. The luminance signal receives the angle modulation 4 after passing through LPF2 and is then supplied to mixer 6 via HPF5. On the other hand, the chrominance signal is led to frequency converter 9 via BPF3 to receive the frequency conversion to the low frequency, and then undergoes angle modulation 11 so that the phase may feature the prescribed value with every integer-fold period of the H period. Then the output of the angle modulation is sent to mixer 6 to be mixed with the angle modulation luminance signal. And the output are recorded alternately via magnetic head 7 featuring different azimuth angles to each other and so that the horizontal synchronous signal recording positions may be adjacent at the adjacent recording tracks. Thus the color S/N in enhanced with reduction of the cross modulation component, the adjacent crosstalk and others. As a result, the steady color picture can be recorded.
