Abstract
A method of recording and/or reproducing color video signal comprises the steps of forming from a color video signal a frequency division multiplexed signal of an FM luminance signal and a frequency converted carrier chrominance signal, recording the frequency division multiplexed signal on a first track on a magnetic tape by one of two heads constituting a pair, forming a high-frequency signal at least including an added signal made up of a high-frequency component of the color video signal and a high-frequency bias signal, recording the high-frequency signal on a second track by the other of the two heads simultaneously as the recording of the first track, demodulating at least a reproduced luminance signal from a signal reproduced from the first track, obtaining at least a high-frequency component of a luminance signal from a signal reproduced from the second track, and mixing the reproduced luminance signal, the high-frequency component of the luminance signal, and a reproduced carrier chrominance signal reproduced from the reproduced frequency division multiplexed signal, or a reproduced carrier chrominance signal separated from the reproduced high-frequency signal. A recording and reproducing apparatus performs recording and reproduction according to the above method.
