る。Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an essential part of an embodiment of the present invention, and FIG. 2 is its flow chart. The signal recorded on the magnetic tape is reproduced by the magnetic head 1, the reproduced signal is amplified by the equalizer amplifier 2, and the signal required for cueing is sent to the control circuit 8 by the no-signal portion detector 3. 4 is an operational amplifier, 5 is an error signal input terminal connected to a personal computer, 6 and 7
Is an interlock changeover switch operated by the control circuit 8, 9 is a tape running device for running a magnetic tape, and 10 is a data output terminal which is connected to a personal computer and outputs a program and data recorded on the magnetic tape.

はテープ走行を止め停止する。It is assumed that the magnetic recording / reproducing device is now reproducing and the personal computer is reading the signal recorded on the magnetic tape. When no error occurs in the personal computer during reproduction of the recording section, that is, when there is no error signal from the input terminal 5, the magnetic tape continues to run, and when the control circuit 8 receives the output of the no-signal section detector 3, Control circuit 8
Stops the tape running and stops.

When input to the control circuit 8 through the input terminal 5, the control circuit 8 causes the tape running device 9 to operate from the reproducing state to the rewinding state. When the control circuit 8 receives the output of the no-signal section detector 3, that is, when it is rewound to the head of the signal recording section, the tape running device 9 is operated again to the reproducing state and at the same time the phase switching switches 6 and 7 are operated. The contact is switched to a contact having a phase different from that in the reproducing state.
