ABSTRACT:
In a cassette for a standard tape player including a platen having an inverted conical hub mounted on the platen to freely rotate about one of the sprocket drive apertures of the cassette with an endless spool of magnetic tape coiled on the hub and platen and having an operating tape loop extending from the spool, the improvement comprising a guide arranged adjacent to one of the capstan drive apertures operable to route the operating tape loop threaded in the cassette to by-pass one of the capstan drive aperture so that placing the cassette in a machine in one orientation will allow one of the capstan drives to transport the operating tape loop, while reversing the orientation of the cassette will not allow a capstan drive to transport the operating tape loop in the cassette in the opposite direction. Also the novel cassette is suitable for use in auto reversing tape players. In the preferred embodiment the guide includes a roller member is arranged on a pivoted arm so that the operating tape loop of the magnetic tape can be positioned to by-pass a capstan aperture in one of the positions of the roller member and not to by-pass this aperture in the other position, thereby allowing the erase functions of a standard cassette player to be employed by the user when desired.
