Abstract: Disc file data read/write head assembly has a slider (56) having an air bearing surface facing the data surface of the disc and a back surface which is attached to a suspension (42) which biases the slider in close proximity to the disc surface, in which the spacing between the slider (56) and suspension (42) is maintained by at least one solder bump (66). Also claimed is the method of controlling the spacing between the suspension and slider as described above and in which the slider is attached to the suspension by adhesive surrounding the solder bumps, and such a slider suspension arrangement in a magnetic disc data storage system.

Abstract: A uniquely configured flexure tongue of a head/gimbal assembly (HGA) provides for parallel positioning of a slider air bearing surface (ABS) during merge and a limitation of pitch of the slider during non-merge. A cantilevered end of the flexure tongue is provided with a finger extension which can be employed for merge operations and a remainder cantilevered end portion adjacent a base of the finger can be employed for limiting pitch of the slider. When a merge comb engages multiple flexure fingers of multiple suspensions in a head stack assembly the air bearing surfaces of the sliders are positioned parallel with respect to one another. This allows maximum disk stack density when a head stack assembly is merged with a head stack assembly. The flexure finger allows various arrangements to be employed for implementing a merge. The present invention also cooperates with a prior art roll limiter so that during merge a three point fixation normalizes a slider at zero pitch.
