ABSTRACT:
A magnetic tape recorder for recording as well as for playback of sound, having a noise suppression device, and sensor member with an abutment surface for engaging against an unopened break through tab of a tape cassette for causing a locking mode for the recording device to be inoperative. The sensor member has an additional abutment surface arranged such that the latter abutment surface senses the wall of the cassette outside of the broken-through penetration opening of the cassette and the insert movement of the sensor member is limited in the opened penetration opening. The sensor member is connected with the locking device; such that in the absence of the limitation due to the absence of a cassette, the locking device, is also inoperative.
