Abstract: An assembly is composed of a transducer (33), an actuator arm (34), an inflatable envelope (30) including two flat surface portions, one of which surface portions is secured to the actuator arm and on the other of which surface portions is mounted the transducer, means (72) for inflating the envelope so as to move the transducer into an operating position and for deflating the envelope so as to return the transducer to a rest position, and reinforcements (40,42,56), associated with the parts of the envelope between the flat surface portions, for maintaining the flat surface portions substantially parallel to each other when the envelope is inflated. … The envelope (30) is formed from a flexible non-elastic material, and the reinforcements (40,42,56), both constantly maintain the flat surface portions substantially parallel to each other and constantly maintain the parts of the envelope between the flat surface portions substantially parallel to each other.

Abstract: AN EXPANDABLE SUSPENSION FOR SUPPORTING A SLIDER AND MOVING IT TO THE DISK IN A DATA RECORDING DISK FILE A suspension for an air-bearing slider 32 in a data recording disk file is an envelope 30 which expands when pressurized air enters the envelope interior. The envelope 30 includes a pair of flat flexible sheets 50, 52, preferably of polyimide, which are secured at their perimeters 54, and stiffeners 40, 42, 56 bonded to the sheets 50, 52 to provide stiffness between the slider 32 and the arm attached to the disk file actuator. Four parallel strips 60, 62, 63, 64 on the polyimide sheets 50, 52 function as hinges so that the envelope expands in the manner of a four-bar linkage, thus moving the slider 32 toward the disk with the slider's air-bearing surface maintained generally parallel to the data surface of the disk. Electrical conductors 80 for connecting the read/write transducer 33 supported on the slider 32 to the read/write circuitry of the disk file are formed on one of the polyimide sheets 50.
