Abstract: A head suspension or head suspension component that includes a spring metal support layer, an insulating layer and a conductive layer, into which three dimensional heat dissipation structures have been integrally formed to dissipate heat from the head suspension, especially in an area adjacent to an integrated circuit mounted on the head suspension. The heat dissipation structures may include a plurality of heat fins formed into or onto one or more conductive traces of the conductive layer, or may include a plurality of projections or indentations formed into or onto conductive traces. Use of a partial etching technique allows for simultaneous etching of both the traces and the heat fins within the traces, thereby decreasing production costs and increasing head suspension reliability. Heat fins may also be formed into the support layer in a region adjacent to the conductive layer heat fins, if desired in order to dissipate even more heat from the region.

Abstract: A disk drive suspension in which resonance characteristics are adjustable and a method for such adjustment. The disk drive suspension includes a load beam, a head mounting region and one or more mass balancing structures. The mass balancing structures are adapted for permanent displacement or removal to adjust mass distribution of the load beam. In this way, resonance characteristics of the load beam can be adjusted. A method of adjustment includes determination of an adjust location on the load beam at which a resonance characteristic to be adjusted is sensitive to changes in mass. The mass distribution of the load beam are adjusted at this adjust location.

Abstract: A magnetic head suspension and method of manufacture of the type having a dimple formed in a surface of the head suspension. The dimple comprises a solid protuberance that is partial etched in a surface of the head suspension and then coined by engaging a socket with the partial etched protuberance to form a convex tip portion. The socket can have a hemi-spherical interior surface to form a hemi-spherical coined partial etched dimple. Alternatively, the socket can have a conical interior surface to form a conical coined partial etched dimple. The dimple can be formed on a slider mounting surface of a flexure to act as a static attitude compensation dimple. Alternatively, the dimple can be formed in a loading region of a load beam or in a cantilever region of the flexure to act as a load point dimple.

Abstract: A method of adjusting the static attitude of a head slider attached to a head suspension for use in a rigid disk drive. The head suspension includes a load beam having a mounting region, a rigid region, and a spring region. The head suspension also includes a flexure for supporting a head slider having a read/write head. The flexure is attached to the load beam at at least an attachment isolation structure. The attachment isolation structure includes an attachment area at which the flexure is attached to the load beam; at least one slot surrounding the attachment area; and at least one junction tab traversing the slot to connect the attachment area to the remainder of the head suspension. The attachment area can be displaced by permanently deforming the junction tab. Displacement of the attachment area places a torque on the flexure which causes a displacement, e.g. adjustment, of the head slider attached thereto.

Abstract: A method for designing and manufacturing a head suspension assembly having a side profile in the radius and rigid regions which is optimized for first and second torsion or other resonance characteristics.

Abstract: A method for manufacturing disk drive head suspensions of the type for supporting a transducer head in a loaded state at a fly height above an information storage disk. A desired loaded state side profile for the suspension is determined, for example, by experimental or numerical techniques. The nature and location of one or more weakening structures on the suspension are then determined. The weakening structures will cause the profile of the suspension to change as the suspension moves from an unloaded state to the loaded state, and to have the desired loaded state side profile when in the loaded state at the fly height. Experimental and empirical techniques can be used to determine the nature and location of the weakening structures. A plurality of the suspensions, each having the weakening structures, are then manufactured. Suspension manufactured by the method can be optimized for resonance and other performance-related characteristics.
