Abstract
PURPOSE: To remove crosstalk signals and carry out high density recording to perform recoding and regeneration for a long time by the use of a tape with short length by comparing phases between non-modulation carrier components of a chrominance signal and non-carrier components delayed for 2H period and detecting the phase variation of chrominance signal.
CONSTITUTION: Non-modulation carrier components Si of chrominance signal Ss is fetched from circuit 131, is entered to the one side of switch circuit 132 and, in addition, is entered to another side of it through inverter 133; moreover output Q22 from FF 122 is applied as a control signal of circuit 132 to components Si. Output Si of circuit 132 is entered to the terminal of one side of phase comparator 134 and the output of circuit 132 is entered to another terminal after delayed for 2H period by delay circuit 135; phase comparison of both signals is carried out, the hue variation of signal Ss is detected 130 and crosstalk signals are removed by a comb line filter. Thus, recording is available without a gard band between adjoining tracks.
