ABSTRACT:
In an apparatus for recording, in successive parallel tracks on a record medium, an audio signal and a color video signal comprised of a luminance signal and a chrominance signal constituted by at least two chrominance signal components, and in which the luminance and chrominance signals are recorded in alternate tracks, respectively, with the chrominance signal components being time-base-compressed and time-division-multiplexed so as to be arranged alternately in sequence in the respective tracks; the audio signal frequency modulates at least one carrier to provide a first frequency modulated output in a predetermined frequency band, the time-base-compressed and time-division-multiplexed chrominance signal components frequency modulate a second carrier to provide a second frequency modulated output in a frequency band above the predetermined frequency band of the first frequency modulated output, the first and second frequency modulated outputs are combined, as in an adder or mixer, the luminance signal is processed, for example, in a frequency modulator, and then supplied to first recording heads for recording in the respective ones of the alternate tracks, and second recording heads receive the combined first and second frequency modulated outputs for recording in the others of the alternate tracks.
