<p>PURPOSE:To achieve program search suitably without malfunction, by detecting nonrecording part surely, through the detection of a low frequency signal recorded on the nonrecording part at fast fowarding and rewinding. CONSTITUTION:An LPF6 passes through only a playback output of a low frequency signal recorded on a nonrecording part, only when a tape speed of fast forwarding and rewinding is faster. A program searching signal based on the detection of nonrecording part is surely generated without being affected to tape noise of the nonrecording part via an amplifier 7 and a level adjusting circuit 8. Thus, suitable program search can be made without malfunction.</p> |
