Patent ID: 8570687

Claim:
A hard drive (HDD) gimbal trace circuit characterized in reduced magnitude of the residual stress or residual plastic strain, the trace circuit comprising: a plurality of traces, the plurality of traces forming a trace structure; and a strut extending substantially along a longitudinal axis configured to support a transducer, the trace structure has a proximal end portion extending outboard and substantially parallel to the strut, and a distal end portion extending outboard and substantially parallel to the strut, wherein the plurality of traces have a high strain region deformed from mechanical-coarse adjustment of the strut; wherein the trace structure has, at the high strain region defined from the mechanical course adjustment of the strut, a characteristic shape of either an outward circle shape or a double outward circle shape; wherein the characteristic shape of either an outward circle shape or a double outward circle shape of the trace structure lies between the proximal end portion of the trace structure and distal end portion of the trace structure.
