Patent ID: 8537499

Claim:
A disk drive suspension comprising: a load beam; and a flexure which is disposed on the load beam, the flexure comprising a gimbal portion configured to mount a magnetic head provided with an electrical element for writing or reading; wherein the flexure comprises: a plate-like metal base made of a stainless-steel base material, the metal base including a first base portion which overlaps and is fixed to the load beam, and a second base portion which extends outside of the load beam and does not overlap the load beam; a slit formed between two opposite side portions of the metal base, penetrating the metal base thicknesswise, and extending longitudinally relative to the metal base; an insulating layer made of an electrically insulating material and formed on the metal base; a first conductor formed within the slit, laminated to a first surface of the insulating layer on a same side as the metal base, and extending longitudinally relative to the metal base along the slit, the first conductor being made of a same stainless-steel base material as the metal base and being electrically connected to the element of the magnetic head, and the first conductor comprising a non-overlapping portion which does not face the load beam and which extends along the second base portion of the metal base, the non-overlapping portion of the first conductor and the second base portion of the metal base being equal in thickness; and a second conductor laminated to a second surface of the insulating layer on a side opposite from the metal base, facing the first conductor across the insulating layer, and extending longitudinally relative to the metal base along the first conductor, the second conductor being electrically connected to the element of the magnetic head.
