Abstract
PURPOSE:To detect an identifying signal without fail by equipping a means to frequency-modulate the identifying signal between the music of a magnetic tape and to record the signal and a means to demodulate this identifying signal and to detect it. CONSTITUTION:The identifying signal, which is frequency-modulated with the one frequency and the half frequency of a >=20Hz and <=1kHz audible frequency, is recorded to the magnetic tape. Accordingly, the identifying signal can be recorded in a short time. In case the magnetic tape is quickly traversed or fed back at an N-fold high speed of a traveling speed at a normal reproducing time in a regular direction or a reverse direction, even when the identifying signal recorded to the magnetic tape is reproduced, the frequency spectrum of the identifying signal is always in the range of a reproducing frequency characteristic. Thus, the identifying signal can be securely detected at a fixed speed traveling and a high speed traveling.
