Abstract
The recording latch is pivotably mountable in a recording cassette between a record position and a no-record position. A plug at the bottom of the latch selectively blocks the record opening in the bottom wall of the cassette, and a flange at the top of the latch is selectively visible through the latch-engaging opening in the top wall. Two tabs are mounted on the flange, and the top wall of the cassette includes a record groove and a no-record groove. The tabs engage the record groove when the cassette can be used in the record mode and the tab engages the no-record groove when the cassette can not be used in the record mode. This engagement system is located entirely on the flange of the recording latch.
