Abstract

PURPOSE: To remove noise between tranks to record PAL color signals with high density by recording chrominance signals in the recording track, advancing the phase of chrominance signal by /4 in every holizontal period in one portion of the track and delaying it by /4 in every holizontal period in another portion of that.
CONSTITUTION: Chrominance signal Ss is picked up by supplying a PAL color video signal from terminal 11 to HPF 31 and is recorded in tape 2 as a recording track by recording systems 11 to 31, head drive servo-circuit 80 and record regeneration alteration switches 91 to 95. In case of the recording, chrominance signal Ss is supplyed frequency converter 33 through ACC amplifier 32, every other field period fixed on Ta and the other field period is fixed on Tb; the phase of chrominance signal is reversed around U axis in every holizontal period with the standard phase of chrominance sybcarrier. Then the phase of chrominance signal Ss is advanced by /4 in every holizontal period in the one portion of the record track and it is delayed by /4 in every holizontal period in the other portion of the record track.
