Abstract
A headlift for a disk drive head suspension extending from a planar base region on a load beam of the head suspension. The headlift is formed from first and second layers of relatively stiff metal separated by a layer of polymer. The headlift includes a headlift tab and a stiffener extending over at least a portion of the headlift tab. The headlift tab includes a convex headlift region formed out of one of the two metal layers. The stiffener is formed from one of the two metal layers or from a combination of the polymer layer and one of the two metal layers.
Claims17
A disk drive head suspension component having a headlift, comprising:
- a first relatively stiff metal layer having first and second opposite surfaces, including:
- a base region;
- and
- a headlift tab extending from the base region and having a convex lift region on the first surface;
- and
- a polymer layer on the second surface of the first metal layer, including a stiffening portion extending from the base region over at least a portion of the tab;
- and
- a second relatively stiff metal layer on at least portions of the polymer layer, including a stiffening portion extending from the base region over at least a portion of the tab.
A disk drive head suspension component, comprising:
- a metal base region including first and second stainless steel layers separated by a polyimide layer;
- and
- a headlift extending from the base region, including:
- a tab formed from the first stainless steel layer and having a lift region with concave surface;
- and
- a stiffener on the concave surface of the tab formed from the second stainless steel layer and the polyimide layer.
