Abstract

PURPOSE: To make possible the effective use of tapes by making possible fresh recording in the tape when no cue signal is recorded in the recording medium even when the miserasing preventing piece to be detected provided to a cassete is not detected with a detecting means.
CONSTITUTION: A detecting plate 4 is disposed on the VTR side, for the erasing preventing pawl 3 of the cassette 2 containing a magnetic tape 1 therein, and a micro SW 6 connected to a control circuit 7 is provided to the lower part. A cue signal track 16 is provided in addition to video tracks 14 and audio tracks 15 to the magnetic tape 1. The signal read head 17 of the track 16 is provided and is connected to the coil 22 of the contol switch 24 for power supply to the plunger 23 connected to the detection plate 4, through a detector 20, inverter 21, etc. When the preventing pawl 3 has been broken away and Q signal is not recorded in the tape, the output of the detector 20 is 0, and is inverted in the inverter 21, by which the coil 22 is energized to close the SW 24. Then the detection plate 4 fowers to close the micro SW 6, by which recording is made possible in the same manner as when the preventing pawl 3 has not been broken away
