Abstract: A head suspension having an alignment structure for minimizing misalignments between a flexure and a load beam of the head suspension. The load beam and the flexure of the head suspension include a first aperture formed near a load point dimple of the head suspension to provide a reference datum. An elongated alignment aperture is formed in the rigid region of the load beam, and a proximal alignment aperture and a distal alignment aperture are formed in the flexure. The elongated the aperture overlaps at least a portion of the proximal and distal alignment apertures in such a manner that the proximal perimeter edge of the elongated aperture encroaches on the proximal alignment aperture and the proximal perimeter edge of the distal alignment aperture encroaches upon the elongated alignment aperture. This configuration of apertures allows the flexure and load beam to be independently aligned relative to each other by pins of an alignment tool that engage the proximal perimeter edge of the distal alignment aperture and the proximal perimeter edge of the elongated alignment aperture.

Abstract: A switchable shunt has an insulating layer separating conductive lead and spring metal layers. The shunt includes a base region formed on the spring metal layer, one or more arms formed in the conductive lead layer and at least one of the insulating and spring metal layers, one or more pad regions electrically coupled to an arm and formed in at least the conductive lead layer, and one or more gaps. Each arm extends through a gap and is resiliently biased toward a shunted state with the pad region in electrical contact with the base region. The shunt is movable to an electrically open state where the pad and base regions are electrically isolated. A method of making the shunt includes etching the shunt from laminated material and pushing the arm and pad through the gap. The shunt may be operated by applying a force to the arm.

Abstract: A head suspension or head suspension component article configured for solder ball bonding of a head slider to electrical traces on article. The article including electrical traces formed from electrically conductive material with the electrical traces having a bonding region adapted for electrical bonding to a head slider. Also included is a support structure providing support for at least portions of the electrical traces and including a head slider mounting region adapted to receive the head slider. This structure is configured to mechanically and thermally isolate the bonding region of the electrical traces from the head slider mounting region to reduce mechanical and thermal effects of a solder ball bonding process on the article during solder ball bonding of the head slider to the electrical traces. The support structure may be reduced at or around the bonding region, or the conductive material may be increased to dissipate more heat.

Abstract: The present invention is a magnetic disk drive head suspension of the type having a load beam and a flexure, including an alignment measurement pattern on either the load beam or the flexure. The flexure is mounted to a distal end of the load beam, and the alignment measurement pattern is used to evaluate and quantify the position of the flexure relative to the load beam. The alignment measurement pattern includes a plurality of openings adjacent a tooling reference hole that are sized and positioned to expose the outer perimeter of a corresponding tooling reference hole. In this manner, the alignment measurement pattern provides an accurate assessment of the alignment between the load beam and the flexure by indicating the offset of the flexure tooling hole relative to the load beam tooling hole.

Abstract: An improved head suspension assembly employs a wider and stiffer load beam and flexure having univeral lateral stiffness and a higher natural frequency. The flexure is a unitary configuration having a pair of rails positioned along opposite sides of the flexure. These rails are produced by bending a portion of the flexure material into a bend to form a projecting member arranged to project toward a surface of the load beam to which the flexure is mounted. In this way, the bend faces away from the load beam for interfacing with a ramp to move a head mounted to the flexure away from a disk. This configuration prevents flexure etched edge contact with the ramp and subsequently chipping or other damage to the head suspension assembly.
