Abstract
An improved tape cassette for use with small size tape recorders which provides mechanical indicating means on the cassette which enables the user to tell which side of the cassette has been utilized and further provides a pair of depressions formed in two rear corners of the cassette which are adapted to receive a sensing lever of the tape machine for preventing erasure of the tape accidentally. The placement of the depressions at the rear corners allow the cassette and the machine with which it is to be used to be made smaller and much easier to align the sensing lever of the recorder, than in the prior art.
