ABSTRACT:
A pair of friction sheets loosely disposed between the opposite end faces of wind-up cores and the inner surfaces of a cassette casing in a magnetic tape cassette are loosely engaged with posts of rotatable guide rollers and guide pins in the cassette so that the opposite side edges of the magnetic tape may be guided by the friction sheets substantially throughout its path and the tape may be fed in a stable manner. Engaging portions of the friction sheets may have protruded portions protruded toward the inner surfaces of the casing to guide the tape with sufficient friction. When the magnetic tape cassette is put into a cassette tape recorder, the tape travels stably with respect to the magnetic head of the recorder.
