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 forked outrigger structure. Attached at the end of each outrigger arm is a spaced-apart flexure tongue structure. 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, thereby permitting decreased disk spacing.

Abstract: A disk drive suspension and method for design of a disk drive suspension where the suspension has a load beam with a rigid portion and a flexure comprising a frame attached to the load beam rigid portion at a welding point. The frame has left and right outriggers and a tongue between the outriggers and cantilevered from the frame at a flexure offset rail. The tongue has a free end for carrying a slider in gimballing relation in operative proximity to a disk. The tongue free end being angularly displaced from said load beam by a dimple at a dimple contact point located according to the formula: I1/I2=(b+c)2/b2 where I1 is the moment of inertia of the flexure tongue (excluding the outrigger portion) I2 is the moment of inertia of the flexure outrigger (excluding the tongue portion) b is the length between the dimple contact point and the edge of the flexure offset rail and, c is the length between the dimple contact point and the welding point, whereby the suspension is substantially free of change in pitch static attitude angle through variations in the vertical height of said dimple and corresponding vertical displacement of said dimple contact point.
