摘要： The present invention relates to a method and apparatus for providing improved roll static angle adjustment for head gimbal assemblies (HGA's) used in disc drives. In the method, proximal and distal clamping members are attached to a load beam of the HGA and are separated by a distance of 4-30% of the length of the load beam. One of the distal and proximal clamping members is rotated about a longitudinal axis of the load beam such that the relative angular position of the distal and proximal clamping members reaches an adjust angle. Also disclosed is a rigid beam section of an HGA that includes apertures which are positioned along maximum stress contours where early plastic deformation of the rigid beam section is desired during adjustment of the roll static angle.

摘要： A disc drive suspension is provided, which includes a longitudinal axis, a rigid load beam section and a preload transfer section. The rigid load beam section extends along the longitudinal axis and has first and second opposing lateral side edges with respective first and second stiffening rails. The first and second stiffening rails are bent out-of-plane with respect to a main body portion of the rigid load beam section and terminate at a distal end of the rigid load beam section. The preload transfer section extends distally from the distal end of the rigid load beam section and has a third stiffening rail. The third stiffening rail is bent out-of-plane with respect to a main body portion of the preload transfer section and extends longitudinally from the distal end of the rigid load beam section.

摘要： An apparatus, method and combination for dissipating vibration from a head suspension of a data storage device. The combination includes a rotating disc in a data exchange relationship with a read/write head supported by a head suspension formed by the method. The method includes the steps of; forming a mounting region and a load beam region each adjacent a bend region; removing material from the bend region to form an aperture, a strut, an isolation aperture and a damping material support structure; and affixing a damping material to the strut and the damping material support structure. The apparatus includes the bend region adjacent both the mounting region and the load beam region, with the damping material attached to the strut as well as to the damping material support structure. The load beam region includes a rigid portion, which supports a flexure upon which a read/write head is attached.

摘要： The present invention provides a system, method and apparatus for controlling the coverage of an adhesive bond area between a suspension and a flex circuit interconnect by etching an area of the suspension to create a bonding area. The etching process prevents bonding of the flex circuit interconnect to the suspension in a tail and a side region allowing movement between the flex circuit and suspension, wherein the movement dampens a first torsion resonance mode. Better control of the bonding area between the interconnect and the suspension using the “adhesive down” helps reduce the variation in the roll stiffness of the suspension thereby reducing the fly height variation.

摘要： A suspension is provided, which has proximal and distal ends and a longitudinal axis extending from the proximal end toward the distal end. A rotating hinge rotates the distal end about the longitudinal axis in response to vertical motion of the distal end relative to the proximal end. In one example, the suspension includes a preformed twist deformation, which rotates the distal end about the longitudinal axis relative to the proximal end axis in a direction opposite to rotation by the rotating hinge, in response to the vertical motion.

摘要： A suspension for supporting a head slider over a media surface. The suspension includes a load beam, a base plate interface region, and a base plate. The load beam has a proximal end, a distal end and longitudinal centerline. A localized stiffening portion is raised above the load beam, and is connected to the load beam by rounded side edges. The base plate interface region is coupled to a proximal end of the load beam, and provides a pre-load bend. Finally, base plate is coupled to the base plate interface region such that the base plate is coupled to a side of the base plate interface region that is opposite the media surface.
