Abstract
A tape drive hub having an improved reel latch, a hub body having a plurality of radial openings communicating with a reel receiving cylindrical surface, a tapered locking member carried axially by the body removable from an unlocked to a locked position, and an actuator received in each of the radial openings, each of the actuators being formed of a cylindrical body having a piston at the outer end and means at the inner end for engaging the locking member, and each actuator cylindrical body including a preloaded spring engaging the piston so that when the locking member is axially advanced into the locked position, each cylindrical body is pushed outwardly to engage the piston end with a reel positioned in the hub, the force of engagement being determined by the preload on each of the actuator springs.
