<p>PURPOSE:To guarantee the consecutive recording by detecting a control signal changed in its duty ratio, controlling a capstan motor in order to make a new recording part recorded from the end of the previous recording part and controlling the recording position on a tape. CONSTITUTION:When the tape is rewound into a cassette, a control signal control circuit 8 is controlled by a system control circuit 1, and the duty ratio at the end part of the tape is changed. That is, the change is made for the control signal in such a way that + time(t1 t3) and - time(t2 t4). At the time of reproducing, the capstan motor is controlled by timing for rising + signal in an output of a control signal waveform shaping circuit 10. At this time, when the tape is wound to come under the recording standby state again, the timing for rising one side control signal changed in the duty ratio is detected by the circuit 1 to control a capstan motor control circuit 11, and then the tape is stopped to be under the recording standby state. By this method, the occurrence of a nonrecording part between the previous recording part and the new recording part is prevented.</p> |
