Abstract:
A flexure mounted on a load beam of a disk drive suspension, including a metal base formed of a stainless-steel plate; and a conductive circuit arranged along the metal base. The conductive circuit includes an insulating layer on the metal base; and a conductor on the insulating layer. The conductor includes a thin conductor portion formed in a first region (A1) which is part of the conductive circuit in a longitudinal direction; and a thick conductor portion formed in a second region (A2) which is another part of the conductive circuit in the longitudinal direction, the thick conductor portion being thicker than the thin conductor portion. The flexure includes a flexure tail portion having an opening formed in the metal base; a bent portion of the metal base which is bent in a thickness direction at the opening; and a trace curved portion curved in the thickness direction at a position facing the opening. The trace curved portion includes the thick conductor portion.
