Appl. No.:

09/439578

Inventors:

Robert Summers - Temecula CA 92591
Amanullah Khan - Temecula CA 92591

International Classification:

G11B 542

US Classification:

2960303, 2960306, 294071

Abstract:

Disk drive suspension load beam and flexible circuit components are juxtaposed and properly located relative to each other before welding by a series of areally distributed locator structures that intersect across the common plane between the components in aligning relation.

Assignee:

Magnecomp Corp. - Temecula CA

International Classification:

G11B 548

US Classification:

360246, 3602459

Abstract:

Excessive capacitive coupling in a wireless disk drive suspension having minimum dielectric film thickness for better mechanical properties is reduced by removing a portion of the wireless conductor immediately opposite the suspension conductors only to obtain reduced capacitive coupling and thus better electrical properties without sacrifice of mechanical properties.

Appl. No.:

09/607255

Inventors:

Robert Summers - Temecula CA

Assignee:

Magnecomp Corp. - Temecula CA

International Classification:

G11B 548

US Classification:

3602455, 3602445

Abstract:

A single piece suspension and actuator arm includes a load beam having an integrated flexure and hinge each formed of the same web as the load beam, the flexure being foldable at the hinge to lie over the load beam engaged therewith to secure the flexure in its folded over condition. The load beam defines an additional attachment structure that attaches to cooperating attachment structure on the actuator arm, with one or more of the attachment structures comprising a tab and slot arrangement.

Abstract:

PZT crystals are peripherally coated in manufacture by cutting a series of intersecting first kerfs in a wafer comprising a plurality of PZT crystal precursors, filling the kerfs with a coating resin, and cutting a second, narrower kerf in the locus of the first kerfs to separate the crystals while providing them a peripheral coating of the coating resin.

International Classification:

G11B 542

US Classification:

3602453

Abstract:

Problems aligning a slider with a dimple in manufacture of head gimbal assemblies for disk drive suspensions are obviated by defining optically readable indicia that serve as a reference for positioning apparatus rather than the dimple.

US Classification:

3602452, 3602453, 3602451

Abstract:

Problems aligning a slider with a dimple post in manufacture of head gimbal assemblies for disk drive suspensions are obviated by defining left and right optically readable indicia that are visible when the dimple post is not and that serve as a reference for positioning apparatus rather then the dimple post itself.

International Classification:

G11B005/48
G11B021/16

US Classification:

3602448, 360245, 3602451

Abstract:

A disk drive suspension having a minimized 2torsion characteristic includes a load beam having a given side profile and centerline rotation axis. The load beam has a base portion, a spring portion, and a beam portion. The beam portion has a distal section supporting a flexure having a tongue. There is a dimple between the tongue and the load beam, and a slider carried on the tongue for gimballing movement about the dimple. The dimple has a given height that displaces said beam portion so that the beam portion side profile is biased from said centerline rotation axis. A bend is placed in the beam portion distal section of a size and location to offset the displacement of the beam portion by the dimple while maintaining the beam portion before said distal section straight. Thus, the beam portion side profile registers with the centerline rotation axis and its 2torsion characteristic is minimized.
