摘要： A station for performing a lapping method to achieve tight dimension controls for both read and write elements of magnetic recording heads is disclosed. A recording head having a read head stripe height and a write head throat height is lapped using a plurality of lapping forces. At least one of the plurality of lapping forces includes a torque force. A lapping wedge angle is controlled using at least one torque force, which controls the offset between the recording head read head stripe height and the write head throat height.

摘要： A composite thin film slider with a protruding R/W device formed by chemical-mechanical polishing to protrude above its substrate and thereby reduce the distance between the R/W device and the recording media. The slider includes a ceramic or non-ceramic substrate with a substantially planar bearing surface, and a R/W device. The R/W device includes an insulator and certain conductive R/W components, deposited onto the substrate's deposit end. The R/W components may include, for example, a magnetic shield layer, a MR stripe layer, and a magnetic pole tip layer, all layered over the deposit end of the substrate. The R/W components protrude from the insulator sufficiently to extend past the substrate's bearing surface. To manufacture this slider, a substrate with the R/W device deposited thereon is polished with a lapping slurry to disproportionately erode the substrate and insulator with respect to the R/W components. The R/W components therefore protrude from the insulator and the ceramic substrate's bearing surface.
摘要翻译：一种复合薄膜滑块，其具有通过化学机械抛光形成的突出的R / W装置，以在其基板上突出，从而减小R / W装置与记录介质之间的距离。滑块包括具有基本上平面的支承表面的陶瓷或非陶瓷基板以及R / W装置。 R / W器件包括沉积在衬底沉积端上的绝缘体和某些导电R / W元件。 R / W组件可以包括例如磁性屏蔽层，MR条纹层和磁极尖端层，全部层叠在衬底的沉积端上。 R / W组件从绝缘体充分突出以延伸穿过基板的支承表面。为了制造该滑块，用研磨浆料抛光其上沉积有R / W器件的衬底，以相对于R / W部件不正常地侵蚀衬底和绝缘体。因此，R / W部件从绝缘体和陶瓷基板的支承表面突出。

摘要： A slider assembly used in a direct access storage device includes electrically conductive bond pads formed on the slider body. A rigid and electrically non-conductive material surrounds and abuts the bond pads. The material and the bond pads form a planar surface. The material prevents the bond pads from migrating and shorting, so that the bond pads can be placed closer together.

摘要： A method of precisely controlling the amount of flatness or curvature in a lapping plate is disclosed. The lapping plate is formed from two layers of metal alloys, such as tin-antimony and steel. A bimetallic effect is exploited to induce a linear expansion in the plate so that the flatness or curvature of the plate is manipulated with thermal cycling. The plate is machined and charged under very specific and tightly controlled temperatures to produce a very robust, flat plate charge. As temperature cycling induces a linear expansion along a single plane across the plate, the resultant flatness change is scalar with temperature, and can be repeated and controlled. When the plate laps magnetic sliders, the plate can be thermally cycled to produce a conical surface and a high crown-to-camber ratio can be achieved.
