Abstract

Typical disk file data head suspension systems, such as that described in U.S. Patent 4,167,765, consist of a load beam, a flexure, and a slider, wherein the slider supports the read/write head. As designed for a linear actuator, the flexure has a high radial stiffness in the accessing direction, moderate stiffness in the tangential direction (i.e., at right angles to the accessing direction), and low pitch and roll stiffness. Often these same suspensions are used with "in-line" rotary actuators. This results in an exchange of the radial and tangential stiffnesses, so that the stiffness in the accessing direction (Image Omitted) is only moderate and the orthogonal stiffness is unnecessarily high. This invention is a universal suspension flexure for both linear and rotary in-line actuators. As shown in Figs.
