Abstract

PURPOSE:To separate a pilot signal securely from an audio signal without influencing the audio signal, by recording the single pilot signal on more than one audio track in an inphase or out-of-phase state in accordance with the kind of a multiple audio signal. CONSTITUTION:A signal obtained by demodulating a multiple audio signal is recorded on more than one audio track, and in accordance with the kind of the multiple audio signal, a single pilot signal is recorded on more than one audio track in an inphase or out-of-phase state. For example, the recording system 10A of a VTR superposes on encoded single-frequency pilot signals Pb and Pc, generated by a generating circuit 20 from the output Pw of a detecting circuit 15 for the multiple control signal, corresponding to the multiple control signal on demodulated audio signals Sb and Sc to record them on audio tracks of a magnetic tape 5. A reproduction system 10B supplies a reproduced control signal Pw' to a generating circuit 40 for the multiple control signal CS, which is generated corresponding to the pilot signals Pb and Pc.
