ABSTRACT:
Information is digitized, and the digital information signals are used to produce frequency modulated signals the instantaneous frequency of which is a function of the content of the digital information signals. The frequency-modulated signals are recorded in alternate tracks with alternate recording heads having air gaps of different azimuth angles. In one embodiment, the recording heads are the rotary heads of a VTR, and the digital information signals are digital audio signals which are recorded in the same tracks as the usual video signals.
