Abstract
Fitted into the record-lockout opening of a recording tape cassette is a reusable record tab which comprises a body that blocks the opening and at least one resilient leg projecting from the body. The leg is bowed to press against an inner ramp of the cassette housing when the record tab is inserted into the opening, thus holding the record tab snugly in position. A small aperture through the external face of the body receives the point of a writing instrument for convenient removal of the record tab. FIGS. 1-4 show a reusable record tab for a VHS videotape cassette, and FIGS. 5-8 show a reusable record tab for a Betamax videotape cassette.
