ABSTRACT:
A write enabling device 30 includes a hexahedron-shaped plug 32 fabricated from resilient material such as polyethylene. The plug 32 is sized to be snugly accepted by the write protect detection cavity 102 of a tape cassette. When the plug 32 is inserted into the detection cavity 102, the writing (recording) feature of the player/recorder is enabled. A flange 42 assists in the removal of an installed plug 32. Other embodiments include a second planar member 568 which may be selectively rotated to cover or uncover an aperture 562 positioned over the write protect detection cavity 102, and a cover member 668 which may be selectively slidably positioned to cover or uncover an aperture 662 positioned over the write protect detection cavity 102.
