<p>PURPOSE:To prevent partial erroneous erasure by providing a function recording a signal showing the inhibition of erasure and recording and the function detecting the signal of the inhibition of the erasure and the recording while operating the erasure and the recording. CONSTITUTION:A detection device 7 is installed so as to be able to detect an inhibition signal recorded on a magnetic tape when a video signal, etc., is recorded by a VTR. The detection device 7 operates so as to stop recording operation by controlling a video signal recorder 4, an audio signal recorder 3 and a control signal recorder 2 so as to stop the erasure of the signal when the inhibition signal recorded on the magnetic tape is inputted. In such a manner, the partial erroneous erasure is prevented by recording or detecting the signal showing the inhibition of the recording.</p> |
