A low profile, high capacity, high performance disk drive includes a plurality of disk surfaces mounted in parallel for simultaneous rotation about an axis. Each of a plurality of data transducer heads for reading and/or writing data to the data surfaces is attached to a slider. A stacked arm actuator for moving the data transducer heads in a radial direction across the disk surfaces includes a supporting arm and a suspension load beam attached to the supporting arm. The suspension load beam connects the supporting arm to the slider. The suspension load beam includes a load dimple bearing on the slider and has opposed stiffening flanges extending in a plane adjacent the slider. The actuator includes a stack of 9 head arm suspension assemblies and the stack has a height of 16.634 mm. An interdisk spacing of less than 1.4 mm provides a height dimension of 14.635 for a stack of 8 disks. Shock and electrical isolation is accomplished using four mounting blocks carrying energy absorbing, highly damped, resilient material.

High capacity, high performance low profile disk drive

A method in which the wires from the heads on an actuator arm can be positioned and attached to the arm electronics automatically. A loadspring manufacturing assembly has a pair of wire carrying and positioning tails and a disposable portion. The disposable portion and the wire carrying and positioning tails each have pegs for controlling the position of the wire and for allowing twisting of the wire pairs for purposes of noise suppression. The wires are positioned about the pegs and twisted. The wires are then bonded to the loadspring assembly. A portion of the wire carrying tail has a window or opening therein. The wires are fanned out and spaced apart as they pass across the window. The wire carrying portion also has a living hinge. A portion of the wire carrying tail which includes a latching window which latches a peg is moved about the hinge and positioned at about a right angle to the loadspring. The disposable portion and the unused tail are removed. The remaining assembly is attached to the arm electronics module through the window with the spaced apart wires.
