Recording apparatus with improved S/N ratio

An information signal recording apparatus for recording an information signal having a predetermined frequency band onto a recording medium, comprising:

• (a) signal separating means for receiving said information signal and for separating the received information signal into a first signal having a first frequency band and a second signal having a second frequency band which is higher than said first frequency band and outputting said first and second signals;
• (b) first recording means for forming a frequency-modulated first signal by frequency-modulating the first signal outputted from said signal separating means and for recording said frequency-modulated first signal onto a first area of said recording medium;
• and
• (c) second recording means for forming a frequency-modulated second signal, which is interleaved relatively to said frequency-modulated first signal, by frequency-modulating the second signal outputted from said signal separating means and for recording said frequency-modulated second signal onto a second area of said recording medium which is different from said first area.

An information signal recording apparatus for recording a first information signal having a predetermined frequency band and a second information signal having a frequency band which is higher than the frequency band of said first information signal, onto a magnetic recording medium, comprising:

• (a) signal separating means for receiving said second information signal and for separating the received second information signal into a first signal having a frequency band which is same as that of said first information signal and a second signal having a frequency band which is higher than that of said first information signal and outputting said first and second signals;
• (b) first recording means having a first magnetic head to record said first information signal or said first signal outputted from said signal separating means onto a first area of said magnetic recording medium by said magnetic head;
• and
• (c) second recording means having a second magnetic head, which is different in azimuth angle of gap from said first magnetic head, to record the second signal outputted from said signal separating means onto a second area of said magnetic recording medium, which is different from the first area, by said second magnetic head.

An information signal recording apparatus for recording a first information signal having a predetermined frequency band and a second information signal having a frequency band which is higher than the frequency band of said first information signal, onto a recording medium, comprising:

• (a) signal separating means for receiving said second information signal and for separating the received second information signal into a first signal having a frequency band which is same as that of said first information signal and a second signal having a frequency band which is higher than that of said first information signal and outputting said first and second signals;
• (b) first recording means for forming a first frequency-modulated signal by frequency-modulating said first information signal or said first signal outputted from said signal separating means and for recording said first frequency-modulated signal onto a first area of said recording medium;
• and
• (c) second recording means for forming a frequency-modulated second signal, which is interleaved relatively to said frequency-modulated first signal, by frequency-modulating the second signal outputted from said signal separating means and for recording said frequency-modulated second signal onto a second area of said recording medium which is different from said first area.
