A video and audio signal recording apparatus comprises a video block, a digital audio signal producing circuit, a modulating circuit for generating an n-value frequency modulated signal, where n is an integer greater than or equal to three, and a recording circuit for recording the n-value frequency modulating signal and a frequency division multiplexed signal from the video block. A video and audio signal recording and reproducing apparatus comprises a first video block, a digital audio signal producing circuit, a modulating circuit for generating an n-value frequency modulated signal, a recording and reproducing circuit, first and second demodulating circuits, a decoder, and a second video block for obtaining a reproduced video signal.
