Abstract
In a magnetic tape recording/reproducing apparatus, magnetic tape is transported between supply and take-up reels which include reel brake assemblies which are simple, reliable and compact. The brake assembly includes a linear stepper motor and a brake pad mounted on a linearly actuated shaft of the stepper motor. Each reel is mounted on a hub driven by a belt and pulley arrangement. Each reel brake assembly is mounted adjacent the pulley with the motor shaft extending radially relative to the pulley. Upon actuation of the linear stepper motor, the motor shaft is moved radially to engage the brake pad with the pulley. In a preferred embodiment, the magnetic tape recording/reproducing apparatus includes coaxial reels which are driven by coaxially mounted pulleys having individual brake assemblies.
