摘要:
The present invention provides a process for controlling the contour of a feature in a transition area made by etching a substrate. This process includes applying a patterned resist mask to the substrate to form a plurality of mask openings and mask land areas. The mask land areas are sized and spaced to a control the contour of a feature on the substrate.

Mounts for securing magnetic disk drive head suspensions to actuator arms. The mounts include structures that snap onto the actuator arm to provide a secure friction fit engagement. The mounts can be efficiently removed to permit rework of the suspension and head components.
摘要:
A gimbal and load beam apparatus for a head suspension for a disk drive having lateral arms with dielectric and conductor layers without metal backing to provide for low pitch and roll stiffness while also having a structural layer attached to the gimbal at proximal and distal locations for high lateral stiffness. The structural layer may be formed of stainless steel and can serve as the load beam and spring region for the head suspension.

摘要:
A head suspension load beam having a longitudinal axis, first and second edges, and first and second opposite side surfaces. The load beam includes a central rail structure extending along at least a part of the longitudinal axis. The load beam also includes a first elongated partially etched portion in the first side surface of the load beam extending along a substantially entire length of the first edge of the load beam, as well as a second elongated partially etched portion in the first side surface of the load beam extending along a substantially entire length of the second edge of the load beam.

A disk drive head suspension includes a load beam, a flexure for carrying a magnetic head slider, a base mounting structure for coupling the head suspension to a disk drive actuation system, a hinge, and a damping material. The load beam includes a proximal end portion and a distal end portion. The flexure is attached to and supported by the load beam. The hinge is attached to the base mounting structure and to the load beam and includes a constraint layer portion extending toward the distal end portion of the load beam. The damping material is located between and in contact with the constraint layer portion of the hinge and the load beam for damping resonance vibrations in the head suspension.
摘要:
A head suspension assembly for a rigid disk drive. The load beam has a mounting region at a proximal end, a rigid region at a distal end and a spring region connecting the mounting region and the rigid region. A pair of rails extend along a portion of the rigid region. The rigid region has a railed region and a non-railed region adjacent to the spring region. A stiffener is attached to the load beam in a multi-layered structure. The stiffener has a proximal portion extending along at least a portion of the non-railed region without extending into the spring region, and a distal portion extending along 50% or less of a length of the railed region closest to the spring region.
摘要:
A headlift on a distal end of a load beam of the type for use in a disk drive suspension, including two distally extending rails transversely spaced from each other, a cross member extending between the first and second rails, and a tab extending from the cross member. The headlift may include arms extending transversely from each rail that engage with each other and with an offset formed in the load beam. In one embodiment, the headlift is integrally formed from the same piece of material as the headlift. In a second embodiment, the headlift is formed from a polymer and attached to the load beam. The method of manufacture, in one embodiment, includes providing a unitary flat load beam member and folding the load beam member and attaching portions of the headlift to the load beam to form the headlift. Alternatively, the load beam may be formed with a structural surface that interfaces with a mounting portion of the headlift.
摘要:
A head suspension assembly including a stainless steel hinge member, an integrated lead flexure and a polymer stiffener member. The stainless steel hinge member includes a proximal mounting region, a beam region having a load point dimple, and a spring region between the mounting and beam regions. The integrated lead flexure is attached to the hinge member and has a slider bond pad engaged by the load point dimple. The stiffener member is molded onto the beam portion of the hinge member and attached by rivets extending through apertures in the hinge member.
摘要:
A method for manufacturing a disk drive head suspension including a load beam, a flexure and a limiter for restricting the range of motion of the flexure with respect to the load beam. The load beam includes an aperture and an engaged portion adjacent to the aperture. The flexure, in an unformed state, includes a slider mounting region and a generally planar engagement structure extending from the slider mounting region. The engagement structure includes a tab portion extending from the slider mounting region and a hook portion extending from the tab portion. During a first forming operation the hook portion is bent around a tooling die to a ninety degree angle with respect to the tab portion. The flexure is then welded to the load beam with the hook portion extending into the aperture. During a second forming operation the tab portion is bent around a tooling die to a ninety degree angle with respect to the slider mounting region. The second forming operation causes the hook to extend over the engaged portion of the load beam. The first and second forming operations can be performed with tooling moving only in a z-direction.
