Abstract: In order to obtain smooth and positive braking, particularly with very thin magnetic tapes, a tape transport is provided which combines dynamic braking with specially configured mechanical braking means. During normal operation, dynamic braking is employed to bring the supply and take-up reel motors to a stop. A motion sensor detects the instant the reels stop and deenergizes a solenoid which holds the mechanical braking sub-system out of action during play and reeling operations. When the solenoid is deenergized, a pair of linked-together pivot arms are pulled into engagement with the reel drums by springs to obtain holding torque when the reels are at rest. The reel-engaging ends of the pivot arms are fitted with brake pads arranged to obtain differential braking torque between the supply and take-up reels according to the tape directions, a feature which is particularly useful when power failure occurs during tape handling operations.
