ABSTRACT:
A magnetic tape cassette is provided with a pair of rotatable reels each having an upper and lower flange formed with suitable gear teeth. A braking assembly is comprised of first and second ratchet pawls pivotally mounted on a support member which is slidably mounted on the housing of the cassette. The first ratchet pawls are spring biased into engagement with one of the flanges of each reel and are adapted to be pivoted upon insertion of a brake release lever into the cassette. The second ratchet pawl engages the other flange of each reel when the support member is in a first position and is disengaged therefrom when the support member is in a second position.
