Abstract

PURPOSE: To reduce the crosstalk between tracks by making good use of the azimuth effect and thus to ensure the high-density recording, by stepping down the chroma FM modulation wave signal of the SECAM signal and then converting the modulation signal into the low frequency to carry out recording.
CONSTITUTION: Input SECAM signal 1 is isolated 2, 3 into luminance signal Y component and chrominance signal C component respectively. Signal C is stepped down 7 to 1/2 and undergoes frequency conversion 8 via the output of carrier generator 9. Then signal C which is converted to the low frequency via LPF10 is applied to adder 6 and then led to magnetic head 11 and 11' featuring different head cap angles to each other so that an azimuth effect may be obtained in the state under which signal C is piled on the lower side of the FM-modulated luminatnce signal (obtained from isolated 2 signal Y through FM modulator 4 and HPF5 ). And then signal C is recorded on the recording medium. When reproducing, the original SECAM signal is obtained at output terminal 23 via almost opposite procedure to that when recording
