Abstract: A disk drive suspension having a minimized 2nd torsion characteristic includes a load beam having a given side profile and centerline rotation axis. The load beam has a base portion, a spring portion, and a beam portion. The beam portion has a distal section supporting a flexure having a tongue. There is a dimple between the tongue and the load beam, and a slider carried on the tongue for gimballing movement about the dimple. The dimple has a given height that displaces said beam portion so that the beam portion side profile is biased from said centerline rotation axis. A bend is placed in the beam portion distal section of a size and location to offset the displacement of the beam portion by the dimple while maintaining the beam portion before said distal section straight. Thus, the beam portion side profile registers with the centerline rotation axis and its 2nd torsion characteristic is minimized.

Abstract: In the manufacture of disk drive suspension flexures, an absence of exposed unplated conductive trace ends at the locus of severing individual flexures from a panel of flexures is achieved by reducing the cross section a portion of the conductive traces at the locus of severing so that the portion preferentially melts upon passage of a current through the conductive traces, severing the portion and encasing the severed ends in melted plastic from the flexure plastic film layer.

Abstract: Optimum pitch attitude during and between slider contact with a disk in a disk drive is provided by articulating the suspension load beam rigid portion intermediate its ends to flex in the unloaded condition to provide a small positive pitch to the slider and to provide a 0° pitch in the loaded condition when the slider is in operating contact with the disk.

Abstract: A flexure for supporting a slider/electromagnetic read/write head assembly for a rotary actuator-type disk drive. The flexure is designed to improve yaw stiffness while simultaneously improving pitch and roll compliance compared to prior art designs. The flexure has a support structure having a pair of forked outriggers. Attached at the end of each outrigger arm is a spaced-apart flexure tongue structure. The width of the flexure at the connection between the tongue and outriggers is less than the width of the flexure at the connection between the support structure and outriggers. A gimbaling dimple is provided on the tongue structure that is positioned such that when a slider is mounted on the flexure, the dimple is positioned at approximately the center of pressure of the slider. As a result of the inventive design, the position of the gimbaling dimple can be moved substantially forward along the flexure, thereby permitting the use of a notched slider assembly, resulting in an overall decrease in the height of the flexure/slider combination.
