Suspension design including shaped gimbal arms having a reduced mass portion along a length thereof

摘要

A gimbal spring for supporting a slider relative to a disc surface. The gimbal spring includes opposed flexure arms extending from a base of the gimbal spring. The flexure arms are designed to support the slider coupled to the gimbal spring via a mounting tab to pitch and roll relative to the disc surface. The flexure arms are formed of elongated members extending from the base to define a fixed end and an extended end. The flexure arms include an intermediate portion between the fixed end and the extended end having a reduced mass, which is less than the fixed end and extended end. The reduced mass enhances the operation characteristics of the gimbal spring.
