Abstract: An improved unitary one-piece head suspension assembly (28), combining a mounting arm (32), a load beam (30) and a read/write head supporting flexure (29), preferably etched of a single sheet of material, is provided for use in dynamic storage devices and rigid disk drives. The number of required components for the HSA is reduced. By eliminating the need for welding a separate flexure to a separate load beam and then to a separate mounting arm, the number of process steps in fabricating the HSA is decreased and the possibility of warpage to the HSA is prevented. Design changes are more easily facilitated by using the present etched unitary mounting arm and suspension assembly.

Abstract: A magnetic head suspension for attachment to a rigid head arm comprises a spring load beam element and a flexure element. The load beam element (14) is formed from material generally having a first thickness. The load beam has a central region (38, 50, 60, 70) having a second thickness, less thick than the first thickness, formed in a spring region (40). The second thickness may be formed by the partial (50, 60) or complete (38, 70) removal of load beam material in the central region. First thickness legs (40, 42) bounding the central region (38) may be formed to be of widest width (W3) at the location proximal to the rigid section of the load beam, and of narrowest width (W4) between the two ends of each leg, thus providing good lateral stiffness and spring rate characteristics.

Abstract: Two HSAs (10, 12) are mounted to a single rigid arm (18) such that the HSAs (10, 12) interleave one another, with a head (36) of one HSA (12) projecting through an aperture (40) on the load beam (22) of the other HSA (10). Thus, the HSA (10) mounted to the top side (14) of the arm (18) will access the disk below the arm (18) itself, while the HSA (12) mounted on the bottom side (16) of the arm (18) will access the disk above the arm (18) itself. Various types of HSAs can be used with the disclosed interleaving or interfitting. Decreased disk-to-disk spacing is achieved by the disclosed arrangement.

Abstract: An electrical head interconnect assembly is fabricated for installation upon the suspension member supporting a magnetic read/write head over a rotating storage disk of a magnetic disk drive. An interconnect is comprised of a film carrier strip (50) upon which conducting elements (52) are positioned and bonded. The conducting elements (52) are routed along a prepatterned carrier strip defining the X, Y and Z coordinate positioning required to mate with a suspension member (54) without manual routing or manipulation. The conducting elements are fixedly spaced with stripped insulation at both termination points of the interconnect (electronics and head) allowing prepositioned, automatable bonding to connective pads. A suspension member (54) positioned and bonded within the strip at appendage sites, completes the installation of the conducting elements (52) upon the suspension. The carrier then serves to secure the conductors and suspension within the protective framework of the strip and provides patterned tooling references (62) until excised upon completion of suspension assembly.

Abstract: An improved low profile magnetic head disk assembly (28) is used with dynamic magnetic information storage devices or rigid disk drives. The HDA (28) includes a head mounted to a suspension, wherein the suspension base plate is an integral part of the actuator arm (34). Each actuator arm (34) is in close registration with a bearing (36). The actuator assembly positions the head in close proximity with the rigid disk (42) surfaces, with the actuator arms (34) positioned exterior to the disks (42) and not passing over the surface of the disks (42). The actuator arms (34) may be a single piece for each disk (42), two pieces (one for each suspension), or three pieces (two actuator arms and one spacer). The center line of the actuator(s), with or without the spacer, is at the center line of the disk, thus reducing the total HDA (28) height.

Abstract: A partially thinned wire support pad (12, 22, 30) of a generally rectangular shape is provided extending laterally from a longitudinal edge of a base plate of a load beam (10, 20, 28). The support pad (12, 22, 30) is cut from sheet material in one piece with the load beam (10, 20, 28) and, during other manufacturing procedures applied to the load beam (10, 20, 28), is partially thinned to a thickness less than the thickness of the load beam (10, 20, 28). In addition to the partial thinning procedure, a smooth radiused convex edge (14, 24) is provided for the exterior perimeter of the partially thinned wire support pad (12, 22, 30). Partial thinning may also be provided to a trough (34) at a base of channel rails (32) to provide an area of reduced thickness to the channel (32) to provide proximal and distal edges of the channel (32) having a smooth well-radiused profile.

Abstract: A load beam element (10) is provided with stiffening and load lifter rails (14) fashioned by making a cut-out or incised flap (18) from a continuous surface of the load beam element and bending the flap (18) out of the plane of the load beam element (10) surface. These stiffening and load lifter rails (14) project from the plane of the load beam surface over at least a portion of the length of the load beam element and are each oriented in length generally parallel to the nearest edge (19) of the load beam. In addition to providing stiffening of the load beam (10), the rails (14) also provide a surface for contact by a head lifter apparatus to lift and lower the HSA toward and away from an appropriate disk surface.

Abstract: A magnetic head suspension (10) has a flexure (18) and load beam (12) structure. The flexure portion includes a first connection arm member connected at a proximal end thereof to the distal apex of the load beam. Head support means are constructed and arranged for supporting a head slider bonded to one face of a bond pad area (26). The distal end of the flexible arms (28) flexibly suspend the bond pad area of the head support means. A stiffening member, adhesively secured to the load beam adjacent the distal end thereof, projects over at least a portion of the flexure portion and has a load protrusion projecting from a surface thereof for engaging the opposite face of the bond pad area, thereby increasing vertical axis stiffness and providing a gimballing point for facilitating tracking of the slider over the surface of a disk.
