Next, when the reproducing device 1 is rewound and reproduced to correct the over-recorded portion, the edit signal 10 output from the microcomputer 7a becomes M.
The idle voltage is set (hereinafter referred to as M voltage), and the microcomputer 7b of the recording machine 2 receives the edit signal 10 to cause the recording machine 2 to operate.
Is set to the rewinding reproduction state, and the video selector switch 13 is switched to the reproduction signal processing circuit 8b side. In this state, while monitoring the rewind screen on the monitor 14, the portion to be cut is corrected by the rewind reproduction, and then the reproduction device 1
When searching for a point to start recording again by speed search, etc., the edit signal 10 output from the microcomputer 7a
Becomes the H voltage, and the microcomputer 7b of the recorder 2 puts the recorder 2 in the recording pause state by the editing signal 10 and switches the video selector switch 13 to the video signal input terminal 11 again.

Next, when the reproducing apparatus 1 is brought into a still image reproducing state at the point where recording is desired to be started again, and reproduction is started, the editing signal 1
0 becomes the L voltage, and the recorder 2 starts recording. Or later,
The above operation is repeated.

In summary, when the magnetic recording / reproducing device is used as a reproducing device at the time of simple editing, when the recording device is rewound and reproduced after shifting from the normal reproduction state to the paused state, When a rewinding reproduction control signal is input during the recording paused state, the rewinding reproduction control signal is sent from the recording paused state to the rewinding reproduction state when used as a recorder. When the control signal changes to the temporary stop, the recording temporary stop state is entered again.
