摘要:
A load beam of a suspension assembly has one or more longitudinal channels in the rigid region between the side edges. The load beam blank (from which the load beam itself is constructed) has a relief means, such as a channel-compensating gap extending through the actuator mounting region from the proximal end to provide additional width of sheet material to the rigid region of the load beam blank and to enable the formation of these longitudinal channels. A method for manufacturing a load beam of a suspension assembly from a generally planar sheet of resilient spring material is described. A load beam blank is shaped to include an actuator mounting region on the distal end, and a rigid region between the actuator mounting region and the distal end. A relief means, such as a channel-compensating gap extends through the actuator mounting region from the proximal end. At least one channel is constructed in the rigid region. The channel preferably extends between the gap and the distal end of the load beam and thereby reduces the width of the gap in the blank.

The present invention provides apparatuses and methods for determining spatial information of a workpiece surface positioned in a predetermined coordinate system. Apparatuses and methods of the present invention can be used to determine one or more coordinates of one or more measurement locations of a workpiece within a predetermined coordinate system. Such coordinates can be used to define points, lines, and/or surfaces of the workpiece within the coordinate system. In one exemplary application, apparatuses and methods of the present invention can be used to determine spatial information of surfaces of head suspensions or head suspension assemblies such as those that are generally utilized in dynamic storage devices such as magnetic disk drives. Such spatial information can be used to determine z-height and/or static attitude, for example.

An optical measurement device for determining at least two parameters of a measurement location of a surface of at least one workpiece positioned in a known coordinate system is described. The device comprises a first light source providing a first measurement beam. The first measurement beam is directed at a first surface of a workpiece. The device also comprises a second light source providing a second measurement beam. The second measurement beam is directed at a second surface of a workpiece facing opposite the first surface. Further, the device comprises a first system of receiving optics. The first system of receiving optics detects the incoming position of the first measurement beam. The first system of receiving optics is positioned on an opposite side of a workpiece from the first light source. Further still, the device comprises a second imaging system. The second system of receiving optics detects the incoming position of the second measurement beam. The second system of receiving optics is positioned on an opposite side of a workpiece from the second light source.

摘要:
An apparatus and method for determining and adjusting the static attitude of a head suspension or a head suspension assembly for use in a dynamic storage device. An apparatus in accordance with the present invention includes a workpiece support and an adjust device, operatively positioned with respect to the workpiece support, for adjusting the head suspension. The adjust device includes first and second clamp portions for restraining a gimbal arm and an adjust body for deforming the restrained gimbal arm while the gimbal arm is restrained by the first and second clamp portions. A method in accordance with the present invention includes determining the planar orientation of a surface indicative of the static attitude of the slider mounting tongue or a slider mounted thereto and controllably deforming an individual gimbal arm of the flexure independently from another gimbal arm of the flexure to introduce a permanent deformation of the gimbal arm thereby adjusting the static attitude of the slider mounting tongue or slider if present.
摘要:
An instrument for measuring both the static attitude and Z-height of a suspension assembly flexure. The instrument includes an autocollimation system for measuring static attitude angles. The autocollimation system is fixedly mounted to a laser point range sensor for measuring Z-height distances. Optics coincidentally direct the beams of light from the collimation system and from the point range sensor system to a measurement point. The optics include at least one reflector or other optical device. The instrument offers accurate distance and angle readings in a shore amount of time with no repositioning of the instrument, the base, or the part to be measured.
