Abstract: A slider adhesion system can be practiced in a data storage device with a flexure suspended from a load beam and a slider mounted to a gimbal tongue of the flexure. The slider can be aligned with an aperture of the gimbal tongue and attached to an adhesion feature of the gimbal tongue with an adhesive layer. The adhesion feature may consist of a plurality of cantilevered tabs extending into the aperture of the gimbal tongue.

Abstract: A method for assembling a head-gimbal assembly of a hard disk drive, the method including the steps of dispensing adhesive onto a top surface of a gimbal tongue, wherein the gimbal tongue is positioned adjacent to a load beam with a dimple extending from its top surface, and wherein the gimbal tongue is configured with at least one support feature that inhibits its deformation toward the dimple when subjected to downward pressure with respect to the dimple; positioning a slider on which a magnetic head is mounted adjacent to the top surface of the gimbal tongue; and pressing the slider onto the adhesive and toward the dimple of the load beam.

Abstract: An apparatus has a slider body that includes an upper surface opposed to a media-facing surface. The slider body has an edge joined between the media-facing surface and the upper surface and facing a coupling region. The slider body includes a first bond pad on the edge and a laser submount coupled to the upper surface of the slider body. The laser submount has a second bond pad facing the coupling region. The apparatus includes a trace-gimbal assembly having first and second electrical traces facing the coupling region and electrically coupled to the respective first and second bond pad via first and second solder joints. An extension of the trace-gimbal assembly extends between the first and second solder joints preventing contact therebetween.
