ABSTRACT:
A rotary actuated arm assembly for positioning a transducer over a data track of a rotating magnetic disk includes a flexure attached to a load beam at one end and to a slider at the other end. The flexure comprises a thin piece of metal having dimple which contacts the load beam at a point. The dimple allows the slider to pitch and roll about the point to accommodate height variations across the surface of the disk. An elastomeric material is bonded to both the flexure and the load beam at a location near or surrounding the dimple. The elastomeric material imparts radial stiffness to the assembly so that the load beam maintains contact with the dimple at the desired point, regardless of the radial movements of the assembly.
