  • Automatic scan tracking mechanism
    Patent number: 5166848
    Abstract: An improved head mounting structure which disposes a beam-like head support assembly for movement about a center hinge. A magnetic recording head is supported at an outer end of the head support beam assembly and a moving coil is supported at an opposite, inner end of the head support beam assembly. A motor drive assembly is disposed at the inner end of the head mounting structure to drive the coil and thereby induce corresponding movement in the head.

  • Tape drive having an improved reel latch
    Patent number: 4284250
    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.
