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.
