Color video signal recording and/or reproducing system

Claim 1

A color video signal recording and/or reproducing system in which a luminance signal (including a synchronizing signal) and a carrier chrominance signal are respectively separated from a color video signal and are respectively converted into predetermined signal forms to be mixed, multiplexed, and successively recorded onto mutually adjacent parallel tracks on a recording medium, and said luminance signal and said carrier chrominance signal respectively having said predetermined signal forms which are obtained from a signal which is reproduced from said recording medium, are respectively returned into the original signal forms and said luminance and chrominance signals then being mixed and multiplexed in order to obtain a reproduced color video signal, recorded positions of horizontal synchronizing signals of the luminance signal contained in the mixed and multiplexed signal not being aligned in the mutually adjacent tracks on said recording medium, said recording system comprising: first frequency converting means for frequency-converting said separated carrier chrominance signal into a low frequency range; first delaying means coupled to said first frequency converting means, for adding a pre-established delay time to said carrier chrominance signal for every recording unit of each track, so that recording positions of each interval of said frequency-converted carrier chrominance signal corresponding to a horizontal synchronizing interval between the horizontal synchronizing signals of the luminance signal are aligned in the mutually adjacent tracks; frequency modulator means for frequency-modulating said separated luminance signal; first mixing means for respectively multiplexing the output luminance signal of said frequency modulator means and the carrier chrominance signal obtained from said first delaying means; and recording means for recording the multiplexed signal obtained from said first mixing means onto said recording medium.
