    摘要: Methods for forming write heads. One method includes forming a mask layer above a pole tip layer; forming a layer of resist above the mask layer; patterning the resist; removing portions of the mask layer not covered by the patterned resist; shaping a pole tip from the pole tip layer; depositing a layer of dielectric material above the pole tip and flux shaping layer, wherein the layer of dielectric material extends about adjacent to the mask layer; depositing a stop layer over the dielectric material, the stop layer abutting the mask layer; and polishing for forming a substantially planar upper surface comprising the mask layer and stop layer. Another method includes depositing a layer of dielectric material at least adjacent the pole tip, wherein the layer of dielectric material extends about adjacent to the mask layer. A further method includes forming dishing in the pole tip.

    摘要: The magnetic head includes a second magnetic shield that is fabricated in a deposition process. The present invention therefore does not require the deposition of the electrically conductive seed layer. In a preferred embodiment, the deposited second magnetic shield is comprised of cobalt zirconium tantalum (CZT). Because the CZT material is relatively soft, it is preferably deposited within an opening formed in a relatively hard RIEable material such as Ta2O5, SiO2, Si3N3, and SiOxNy, such that a subsequent chemical mechanical polishing (CMP) step can be conducted down to the surface of the relatively hard layer.

    摘要: A write element for use in perpendicular magnetic recording. The write element including a write pole and a self aligned wrap around shield that can have a trailing shield gap thickness that is different from its side shield gap thickness. The materials making up the trailing shield gap and the side shield gaps can be different materials or can be the same material deposited in two different steps. The side or wrap around portions of the trailing shield can extend down to the level of the leading edge of the write pole or can terminate at some point between the levels of the leading and trailing edge to form a partial wrap around trailing shield.

    摘要: A magnetic write head and method of fabrication, in accordance with one embodiment of the present invention, includes depositing a first hard mask layer on a layer of magnetic material, depositing a second hard mask layer on the first hard mask layer, depositing a third hard mask layer on the second hard mask layer and forming a soft mask upon the third hard mask layer defining a write pole. The third hard mask layer exposed by the soft mask is etched utilizing a first chemistry, wherein the pattern of the write pole is transferred from the soft mask to the third hard mask. The second and first hard mask layers exposed by the patterned third hard mask are etched utilizing a second chemistry thereby forming a first and second hard mask. The selectivity of the second chemistry favors the first and second hard mask layers over the third hard mask. The layer of magnetic material exposed by the first hard mask is milled such that a beveled write pole is formed. The selectivity of the milling favors the magnetic material over the first hard mask
