Abstract

PURPOSE: To prevent malfunction even when discrimination of signal and noise is difficult by recording the signal of a low frequency on the same track as audio signal, as an automatic stop signal.
CONSTITUTION: The audio signal supplied from terminal AU at the recording is supplied to a recording head 5 via high-pass filter 1, mixer 2 and amplifier 3 and is recorded in a recording medium I. After the desired audio signal has been recorded, the burst waves of the sutomatic stop signal and control signal from terminal SC are supplied to the mixer 2 and are recorded. At this time, the low frequency component of less effect on the articulation of voice is removed by the filter 1 and the signal of the frequency within this removed low frequency range is supplied and recorded as an automatic stop signal and therefore, the articulation of the voice is hardly impaired and yet misautomatic-stopping may be reduced.
