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.
