Claim:
A magnetic tape cartridge, comprising: (a) a cartridge casing; (b) a tape reel which is contained within the cartridge casing and which is configured to rotate within the cartridge casing; (c) a brake assembly which is movable between an operative state that prevents rotation of the tape reel and a non-operative state that permits rotation of the tape reel, wherein the brake assembly includes: (i) a non-rotatable brake member, and (ii) a brake release member which is rotatably coupled with the tape reel and which is movable along a direction that extends from the tape reel toward the non-rotatable brake member, the brake release member defining a set of projections that extend in the direction from the tape reel toward the non-rotatable brake member in order to push the non-rotatable member such that the brake assembly moves between the operative state and the non-operative state.
