Abstract: The present invention provides a head supporting arm that allows for laser tacking while having a merging lip and limiters for loading/unloading respectively. A head supporting arm according to the present invention includes a load beam, and a flexure connecting the load beam to a slider. The load beam having a dimple for generating a gimbal motion between the flexure and the slider. The slider having a head connected to its one end. The head supporting arm of the present invention further including an exposure opening formed in the load beam. The exposure opening allowing for the exposing of the bonding portion of the flexure that is bonded to the other end of the slider. The exposure opening further providing an opening to extend the limiters formed unitarily with the flexure 36 onto a surface of the load beam that is opposite to the surface on which the flexure 36 is provided. The extended limiters are hooked to the load beam at the opposite surface.

Abstract: A method of assembling a head gimbal assembly. The method comprises a series of steps which include: stacking a base plate, a load beam, and a flexure to form a three-layered stacked series with at least a bottom layer being a base plate series; joining portions of the load beam to the base plate, and the flexure to the load beam in the three-layered stacked series to make a suspension section; attaching a slider to the flexure in the suspension section to make a head gimbal assembly; load-bending a hinge portion formed in the head gimbal assembly; and heating the hinge portion in order to adjust a bending load on the hinge portion at a predetermined bending angle to a predetermined value.

Abstract: Apertures are formed in the portion of a flexure adjacent to the soldered portions between the bonding pads of the slider and the lead pads of lead end portions. With this, an adhesive agent for bonding the slider to a flexure tongue is moved downward from the apertures so there is no fear that the adhesive agent will contact the lead pads and the bonding pads. This design prevents the protrusion of an adhesive agent from short-circuiting the flexure, and absorbs a warp produced by shrinkage of a soldered portion by decreasing rigidity of the flexure. When both the bonding pad formed on the slider and the lead pad of a lead fixed to the platform of the flexure are disposed and soldered, the quality of the soldered portion is improved by locating the pads as close to each other as possible.
