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.
