Varying thickness partial etch rails for disk drive head suspensions

摘要

A load beam or load beam component having rails for use with a disk drive head suspension. The load beam or component is formed from a sheet of material having a first thickness. One or more polygons, beams or other structures having the full first thickness are formed in the rails by partial etching other portions of the rails to a non-zero second thickness that is less than the first thickness. The multi-thickness structures in the rails enhance the operational performance characteristics of the load beam or load beam component.
