ABSTRACT:
A recording and reproducing apparatus includes three groups of magnetic heads. A sound signal is converted into a corresponding frequency-modulated signal and is also converted into a corresponding digital signal. The frequency-modulated sound signal is recorded into and reproduced from a magnetic tape via the first group of magnetic heads. The digital sound signal is converted into a corresponding quadrature phase shift keying signal. The quadrature phase shift keying sound signal is recorded into and reproduced from the magnetic tape via the second group of magnetic heads. A video signal is recorded into and reproduced from the magnetic tape via the third group of magnetic heads.
