<p>PURPOSE:To obtain a reproducing device which facilitates recording signal identification by generating information at the time of the detection of a no- sound part of an audio input and recording it on a medium together, and performing traveling control with information on a reproduced no-sound part. CONSTITUTION:Information DA recording a specified record start part is supplied and when it coincides with the counted value of a counter 84, a capstan is controlled through a monostable multivibrator MM86. When the audio signal after PCM processing enters a no-sound part, an MM157 is triggered, outputs of comparing circuits 158 and 159 fall to L at specific timing, and the output of an AND gate 161 is inverted to H; and an AND gate 163 supplies pulses of an MM160 to a counter 165, which generates a Q output H after counting up continuously to control the capstan, stopping the tape. The counter 165 is reset by an inverter 162 and an AND gate 164 and when an MM167 and an OR gate 166 detect that once, the counter 165 does not operate a while. Consequently, an audio signal recording and reproducing device which easily identifies a recording signal by heat black detection is obtained.</p> |
