摘要：An information signal recording apparatus for recording an information signalhaving a predetermined frequency band onto a recording medium, which comprisessignal separating means for receiving said information signal and for separating thereceived information signal into a first signal having a first frequency band and a secondsignal having a second frequency band which is higher than said first frequency band andoutputting said first and second signals; first recording means for forming a frequency-modulated first signal by frequency-modulating the first signal outputted from saidsignal separating means and for recording said frequency-modulated first signal onto afirst area of said recording medium; and second recording means for forming afrequency- modulated second signal, which is interleaved relatively to said frequency-modulated first signal, by frequency- modulating the second signal outputted from saidsignal separating means and for recording said frequency-modulated second signal ontoa second area of said recording medium which is different from said first area.
