ABSTRACT:
A tape cartridge having a reel lock in the hub that is capable of releasing the reel at the same time the drive mechanism engages the hub while minimizing the vertical travel necessary to provide a robust lock. The cartridge includes a housing and a tape reel in the housing. A tape drive interface on the reel, usually a circular gear on the reel hub, is accessible to the drive mechanism on a tape drive through a hole in the bottom of the housing. An arm is mounted in the hub. The arm moves between a first position in which the arm engages the housing to prevent the reel from rotating in at least one direction, and a second position in which the arm does not engage the housing and the reel is free to rotate in both directions.
