ABSTRACT:
A cassette for accommodating a magnetic tape designed for use in a magnetic recording and/or reproducing apparatus includes a protective covering provided at an access opening of the cassette into which access opening a transducer head assembly is adapted to project to contact a portion of the magnetic tape. The protective covering is movable between projected and retracted positions and, when held in the projected position, shields such portion of the magnetic tape. When the protective covering is moved to the retracted position, that portion of the magnetic tape is located outside the cassette for permitting the transducer head assembly to contact the magnetic tape. The cassette is further provided with a braking lever which applies a braking force to both of the cassette reels to prevent the magnetic tape from being loosened.
