International ClassesG11B 005/54G11B 021/18 AbstractA gimbal flexure and electrical interconnect assembly for attachment to a disk drive suspension assembly. The gimbal flexure and electrical interconnect acts both as an interconnect system for relaying electrical signals and as a gimbal flexure. It comprises a self-supporting set of generally parallel traces--electrically insulated linear substrate-free conductors constructed of a single layer spring material. The set of traces includes a load beam portion extending over and matching the surface topology of at least a section of the first surface of a load beam, and a gimbal portion located at a distal end of the set of traces shaped as a gimbal flexure means. The invention describes specific embodiments, including head harnesses, suspension assemblies, and head suspension assemblies, as well as manufacturing methods.Other References
