ABSTRACT:
In a stereo sound digital recording system in which a plurality of tunes or programs are sequentially and digitally recorded on a magnetic tape, the left and right analog input signals are combined and converted to a digital signal. The analog input signals are also applied to a detector which detects the head of the program or tune and which causes to be generated a start identification sub-code signal which is automatically added to the digital signal, before the modulation thereof, and which is recorded on the tape for about nine seconds in the non-sound portion preceding the tune or program. A second sub-code signal, in the form of a program number signal, may also be added to the digital signal, simultaneously with the program start identification sub-code signal, to provide recorded numbers respectively identifying programs which are sequentially recorded on the tape.
