ABSTRACT:
A magnetic head suspension assembly has certain structural improvements to increase head suspension dynamic performance. Load beam planar surfaces near the flexure may have relief channels to avoid interference between the load beam and the flexure arms, to facilitate flexible head gimballing, reduce pitch and roll stiffness, and maintain dimple contact in the plane of the load beam surface. An extended lifter portion at the load beam distal end may extend beyond the flexure. The flexure relief channels may extend to load beam distal end as stiffeners. A length of tubing may be on both longitudinal edges of the load beam improve suspension damping characteristics. One or both tubes may enclose conductors for signals from the magnetic head. A planar protuberance on the flexure tongue may contact a protuberance on the load beam element near the load beam distal end. Alternatively, the planar protuberance contacting surface may be on the load beam element to contact a protuberance on the flexure tongue. A protuberance on the load beam with reverse rails provides improved resonance. Reverse rail stiffening flanges project from load beam edges, and one or both of the stiffening flanges may have cut-away portions at the load beam distal end.
