Abstract
A reel brake of a magnetic tape single-reel cartridge is released by a contact member positioned in non-rotational contact with the reel brake release button to prevent wear, vibration and noise in the mechanism. One embodiment places a spindle in a centering cone of a hub which operatively engages the tape reel. The centering cone rotates relative to the spindle which is in stationary contact with the release button. A second embodiment involves use of a non-rotating center shaft of a motor which has a rotor that rotates about the shaft. The stationary shaft contacts the release button. A third embodiment extends a stationary post through a hollow rotating motor shaft to contact the release button.
