摘要： An apparatus for loading and unloading air-bearing sliders relative to their respective disk surfaces in a data recording disk file includes an elongated rod mounted on the disk file actuator arm for flexing the suspensions and attached sliders away from their respective disk surfaces. The elongated rod is located in the central longitudinal openings of the actuator arm and is movable to a first position by means of a lever when the lever is contacted by a rotatable cam supported on the disk file frame. When the cam is rotated out of engagement with the lever, a spring forces the rod out of engagement with the suspensions, thereby permitting the suspensions to act in the conventional manner to bias the sliders toward their respective disk surfaces. The sliders are thus only loaded and unloaded relative to the disk surfaces when the disks are rotating at a speed sufficient to prevent the sliders from sticking to the disk surfaces.

摘要： A keyboard (61) includes plural keybar actuators (11) each including plural keys (19, 23, 27, 31) hingedly interconnected (25, 29, 33) and a sensing device (13). The keys of a keybar actuator are all actuated by a common finger (45) in touch typing and therefore are not jointly actuated. Depression of one key causes the keybar actuator (11) to pivot and the sensing device (13) indicates which key is depressed depending upon the amount of keybar actuator rotation. Alternate sensing devices include individual contact switches (79-81) associated with each key.
