摘要：A video and audio signal recording apparatus comprises a video block (12), adigital audio signal producing circuit (24), a modulating circuit (25, 26, 27) for generatingan n-value frequency modulated signal, where n is an integer greater than or equal tothree, and a recording circuit (17, 18, 32, 33) for recording the n-value frequencymodulated signal and a frequency division multiplexed signal from the video block. Avideo and audio signal recording and reproducing apparatus comprises a first video block(12), a digital audio signal producing circuit (24), a modulating circuit (25, 26, 27) forgenerating an n-value frequency modulated signal, a recording and reproducing circuit(17, 18, 32, 33), first and second demodulating circuits (58, 59, 60), a decoder (61, 62R, 62L,63R, 63L, 64R, 64L), and a second video block (52) for obtaining a reproduced video signal.
