ABSTRACT OF THE DISCLOSURE An apparatus for recording and reproducing an information signal comprised of a video signal and two channels of audio signals from an audio signal source in a plurality of successive tracks on a record medium, each track being divided into at least two sections, comprising circuitry for generating the two channels of audio signal from the output of the audio signal source; an A/D for converting the audio signals into digital form; a compressor for compressing the digitized audio signal; first recorder for recording the compressed digitized audio signal in the plurality of successive tracks such that one field interval of the video signal is recorded in at least one of the sections of each track and one field interval of the digitized audio signal is recorded in another section of each track; circuitry responsive to the out- put signal of the audio signal source for generating an identification signal representing the contents of the output of the audio signal source; second recorder for recording the identification signal; a read-head for reproducing video signal, digitized audio signal and the identification signal recorded on the record medium; circuitry for expanding the reproduced digitized audio signal; circuitry for reconverting the expanded digitized audio signal to two channels of audio signal; and a circuit responsive to the reproduced identification signal for generating output audio signals from the outputs of the re- converting means.
