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 is adapted to project to contact a portion of the magnetic tape. The protective covering is movable between opened and closed positions and is normally biased to the closed position to shield such portion of the magnetic tape from the outside. When the protective covering is moved to the opened position, such portion of the magnetic tape is exposed to the exterior of the cassette for permitting the transducer head to contact such portion of the magnetic tape. The cassette is further provided with a braking lever which applies a braking force to both of the reels to prevent the magnetic tape from being loosened.
