<p>PURPOSE:To reproduce a rear surface for a short time without a deck operation even when a lot of not sound recorded parts remains by providing a means to record the inverting signal to a tape and a means to invert a reproducing surface (sound recording surface) of the tape when the inverting signal is detected during the reproduction. CONSTITUTION:An inverting signal generating device 1 generates a special inverting signal, connected to a sound recording amplifier 3 by a sound recording signal selecting switch 8 and then, the inverting signal is sound-recorded to the tape. When the inverting signal detecting device 2 detects that the signal which passes through a head amplifier 4 at the time of reproduction, is an inverting signal, the reproducing surface (sound recording surface) of the tape is inverted, a motor driving circuit 5 receives the detecting signal from the inverting signal detecting device 2 and the driving of the motor for travelling the tape is inverted so that the travelling of the tape can be inverted. Consequently, by operating a sound recording signal selecting switch 8 and recording the inverting signal at the tape at the time of completing the sound recording, even when the long not sound recorded parts remain at the tape, it can be prevented that a silent condition continues for a long time at the time of reproduction.</p> |
