Abstract
Abstract This device relates to video recorders and in particular, to a device for replacing a previously removed record saftey tab. This two-piece device provides a safe, simple, and secure means of re-recording over a tape, and will remain in place on the cassette. One piece is permanently attached to the inner rear wall of the cavity and the second (which is removable) mates to the first. They are color coded for easy recognition and will not interfere with the normal operation of the VCR.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
A device that will allow recording on a video tape cassette that has had its safety break-off tab removed, comprising: (a) a female part of such size as to be securable in a cassette break-off tab cavity by either an adhesive medium or by a friction fit wherein the thickness of said female part is small enough to prevent activation of a recording micro switch sensor in a video cassette recorder; (b) a male part of such thickness that when attached to said female part positions a switch contacting surface of said male part substantially flush with the outside of tape cassette housing; (c) said male part being attachable to said female part by means of an extruded member or plurality of members which fit into corresponding shaped cavities in said female part allowing the two parts to mate whereby said switch contacting surface of said male part is positioned to come in contact with the micro switch sensor and engage the sensor in an on position allowing tape to be able to receive recorded signals; (d) said male part being detachable from said female part to alternatively prevent recording on the cassette tape.
