Abstract

PURPOSE:To perform additional recording at only an unrecorded part with extreme ease, by detecting a recorded part and an unrecorded part on a magnetic tape, and switching a recorded state and an unrecorded state on the basis of the detection signal. CONSTITUTION:A signal recorded on a magnetic tape E is detected by a detection head C, whose detection signal is supplied to a control circuit 2. The output of this control circuit 2, when a signal is recorded on the tape E, turns off a display device 8, a bias oscillating circuit 5, and a muting circuit 1 respectively. Then, the head C detects an recorded part and when the unrecorded part reaches a recording head D a specified time later, the state of the control circuit 2 is inverted. Namely, a display device 8 shows that recording is possible, and the bias oscillating circuit 5 and muting circuit 1 turn on respectively, so that a signal from a recorded-signal source A is recorded on the tape E. Thus, additional recording is performed at only the unrecorded part with extreme ease.
