ABSTRACT:
A magnetic recording tape cassette includes a cassette casing for accommodating a pair of hubs around which a magnetic recording tape is wound. The casing is provided, in the front face thereof, with a magnetic head receiving opening and a pair of tape guide member receiving openings on opposite sides of the magnetic head receiving opening. A pair of resiliently displaceable tape supports are provided in the casing to be opposed to the respective tape guide member receiving openings. The tape supports cause the tape to span the magnetic head receiving opening in parallel to the front face of the casing when the cassette is not loaded in a tape recorder. The tape recorder is provided with a pair of tape guide members which are on opposite sides of the magnetic head and are inserted into the tape guide member receiving openings when the cassette is loaded into the tape recorder. Each tape guide member has a pair of collars spaced from each other by a distance substantially equal to the tape width and smaller than the length of the tape support. When the tape guide members are inserted into the corresponding openings, the collars push the tape supports away from the tape with the tape being accommodated between the collars. The tape is guided by the tape guide members during recording and reproduction.
