ABSTRACT:
In an apparatus for recording video and audio signals, and in which a video signal has its time base compressed to 1/N the time base of a standard television signal and the time base compressed video signal is recorded in slant tracks on a tape by rotary heads while the tape is driven so as to provide a recording format coincident with that of a standard video tape recorder, and with video information of one field being recorded in each track; there are further provided a time base compressor for compressing the time base of an input audio signal in correspondence to the time base compressed video signal, a frequency modulator for frequency modulating a carrier signal with the time base compressed audio signal, and a mixer for mixing the time base compressed and frequency modulated audio signal with the time base compressed video signal prior to recording with the latter by the rotary heads in the standard recording format.
