ABSTRACT:
A magnetic tape cassette is described in which there is provided a cavity in a rear wall of the cassette body for receiving a cavity sensing mechanism mounted internally in a cassette recording apparatus. The mechanism serves to enable and inhibit recording circuits in the apparatus as a function of its access to the cavity. A sliding door having at least two positions is provided to selectively open and close the cavity to the sensing mechanism to thereby provide control over the recording functions of the apparatus.
