Abstract
A recording cassette has a latch that pivots between two positions. A plug at one extremity of the latch either blocks or unblocks a record/not record opening at an under wall of the cassette while a relatively large flange at the other extremity of the latch can either be seen or unseen at the label wall to indicate the record/not record status. By making the latch of a color that contrasts with the label wall, mistakes in observing the record/not record status are virtually precluded.
