ABSTRACT:
An erasure preventing button for preventing recording on a magnetic tape cassette slides within a cavity in a side wall of the cassette between a released position and a depressed position. The erasure preventing button includes a base, which interacts with the tape recorder when the button is released, and a front wall. The front wall includes an arm with a shoulder which is biased toward an opening formed in the side wall of the cavity. The shoulder extends into the opening when the erasure preventing button is released and includes a planar inclined surface which frictionally engages one corner of the opening to prevent the button from sliding from the released position to the depressed position. A rear arm extending from the base prevents the erasure preventing button from being removed from the cavity.
