Abstract

PURPOSE:To perform reproduction by making an automatic and rapid search for the next recording part by taking up a tape rapidly on detecting its unrecorded zone automatically, by providing a waveform shaping circuit, control signal generating means, unrecorded zone detecting circuit, etc. CONSTITUTION:Waveform shaping circuit 2, unrecorded zone detecting circuit 5, a control circuit, etc., are provided to place a tape driving mechanism in fast-forward mode in response to an unrecorded zone detection signal. For example, the output of head 1 is amplified and waveform-shaped into a pulse string signal, which is inputted to counter 6 as a clear input and when an unrecorded zone part on a tape is detected, counter 6 starts counting up and generates output Qn a prescribed no-signal time later. With the output, FF7 is set to hold output Q at the high level, and one-shot multivibrator 8 generates an unrecorded zone detection signal. Consequently, logic circuit 15 outputs high-level control signal (a) and also sends control signal (c) to place the tape driving mechanism in fast-forward mode.
