Abstract

PURPOSE: To achieve a good dubbing processing by taking out luminance signals from the demodulator of the luminance signal path of a recorder for reproduction and taking out chrominance signals from the chrominance signal path as they were converted to a low band and mixing these signals to use them for dubbing.
CONSTITUTION: In the magnetic recording system where luminance components and chrominance signals are mixed and recorded on a magnetic recording medium after luminance components of composite color video signals are FM-modulated and chrominance signals are converted to a low band, switch 130 is provided which connects recording recorder 12 to the output of luminance demodulator circuit 24 of reproducing recorder 10. Further, switch 134 for by-pass which gives luminance signals demodulated at terminal 100 to AGC circuit 108 directly without passing through LPF 105 and switch 132 which connects recording recorder 12 to the output of chrominance ACC circuit 36 of reproducing recorder 10 are provided, and luminance components are given to mixer 116 through HPF 112 and recording amplifier 114 after being FM-modulated.
