Abstract: A magnetic write head for data recording having a magnetic write pole with a stepped magnetic shell structure that defines a secondary flare point. The secondary flare point defined by the magnetic shell portion can be more tightly controlled with respect to its distance from the air bearing surface (ABS) of the write head than can a traditional flare point that is photolithographically on the main pole structure. This allows the effective flare point of the write head to be moved much closer to the ABS than would otherwise be possible using currently available tooling and photolithography techniques. The write head also includes a non-magnetic spacer layer formed over the magnetic shell structure that is recessed from the ABS by a distance that is greater than that of the magnetic shell portion. A magnetic shield is formed over the magnetic shell and non-magnetic spacer.

Abstract: One preferred method for use in making a device structure with use of the resist channel shrinking solution includes the steps of forming a first pedestal portion within a channel of a patterned resist; applying a resist channel shrinking solution comprising a resist channel shrinking film and corrosion inhibitors within the channel of the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel of the patterned resist; removing the resist channel shrinking solution; and forming a second pedestal portion within the reduced-width channel of the patterned resist. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pedestal during the act of baking the resist channel shrinking solution.

Abstract: A method for forming a tapered, electroplated structure. The method involves forming a first mask structure having an opening. A shrink material is deposited into the opening, such that the thickness of the shrink material is less than the thickness of the first mask structure. The first mask structure and the shrink material are then heated causing the sides of the opening in the mask structure to bulge inward. The shrink material is then removed, and a first electrically conductive material can then be electroplated into the opening to a thickness that is much less than the thickness of the mask. The bulbous shaped of the deformed photoresist mask forms a taper on the first electrically conductive material. The first mask can then be removed and a second electrically conductive material can be electroplated over the first electrically conductive material.

Abstract: A method and structure for reducing corrosion during the manufacture of perpendicular write heads is disclosed. Auxiliary pole structures (otherwise known as trailing shields and wrap around shields) are susceptible to corrosion due to their iron containing composition and small dimensions. The impact of corrosion can be reduced by utilizing a gap material comprising an upper surface of noble metals, which extends from underneath the auxiliary pole and is exposed to the same corrosive environment during processing. The area of the exposed gap material is limited to optimize corrosion protection.

Abstract: A method for making a master disk to be used in the nanoimprinting process to make patterned-media disks uses an electrically conductive substrate and guided self-assembly of a block copolymer to form patterns of generally radial lines and/or generally concentric rings of one of the block copolymer components. A metal is electroplated onto the substrate in the regions not protected by the lines and/or rings. After removal of the block copolymer component, the remaining metal pattern is used as an etch mask to fabricate either the final master disk or two separate molds that are then used to fabricate the master disk.
