ABSTRACT:
A method of controlling the spring rate of a spring region of an unassembled or partially or fully assembled load beam for a disk drive head suspension by providing the spring region with a number of bridges which may then selectively opened to achieve a target spring rate. Adjusting the spring rate in this manner provides control of resulting performance characteristics of the head suspension. In one aspect, a data set of spring rate reductions corresponding to bridge sets removed is predetermined and used with the corresponding type of load beam to determine the bridges to remove to approximate the target spring rate.
