<p>PURPOSE:To completely attain the recording of information within a fixed period of time by superimposing and recording the information in the vicinity of the termination of the effective recording area of first and second recorders to both recorders. CONSTITUTION:Setting circuits 23 and 24 give a rewinding setting signal to respective tape travelling devices 21 and 22 while they operate a starting operating part, generate a starting signal and correspond to the signal, and VTRs 1 and 2 become the rewinding condition. When one side rewinding of the VTRs 1 and 2 is completed, a rewinding completing deciding circuit 25 detects it and for example, a recording starting signal is given to a first recording setting circuit 26. Next, even when rewinding of other VTR 2 is completed, a recording starting signal is not given to a second recording setting circuit 27. The VTR records the signal of an input terminal 3. When the rewinding completion is detected by a deciding circuit 25 and the recording starting signal is generated, it is inputted to a timer 28 and a pulse is repeatedly generated, it is inputted to a timer 28 and a pulse is repeatedly generated with a constant time T as a period. The recording due to the VTR 1 is advanced, the timer 28 gives the recording starting signal to the circuit 27 in the vicinity of the tape termination and athe VTR 2 starts the recording, as well.</p> |
