摘要： A magnetic write head for perpendicular magnetic data recording. The write head includes a substrate and a magnetic write pole formed on the substrate, the write pole having a trailing edge and first and second sides. A magnetic stitched pole is formed over a portion of the magnetic write pole, the stitched pole having a front edge that defines a secondary flare point. First and second non-magnetic side walls are formed at the first and second sides of the write pole. The non-magnetic side walls extend from the substrate at least to the trailing edge of the write pole in a first region near an air bearing surface and wherein the first and second non-magnetic side walls extend from the substrate to a point between the substrate and the trailing edge, allowing the stitched magnetic pole to extend partially over the sides of the write pole.

摘要： A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes forming a write pole, and then depositing a refill layer. A mask structure can be formed over the writ pole and refill layer, the mask structure being configured to define a stitched pole. An ion milling or reactive ion milling can then be performed to remove portions of the refill layer that are not protected by the mask structure. Then a magnetic material can be deposited to form a stitched write pole that defines a secondary flare point. The stitched pole can also be self aligned with an electrical lapping guide in order to accurately locate the front edge of the secondary flare point relative to the air bearing surface of the write head.

摘要： A magnetic write head for perpendicular magnetic recording having a write pole with a concave trailing edge. The magnetic write pole can have a trapezoidal shape with first and second laterally opposed sides that are further apart at the trailing edge than at the leading edge. The write head may or may not include a magnetic trailing shield, and if a trailing shield is included it is separated from the trailing edge by a non-magnetic write gap layer. The concave trailing edge improves magnetic performance such as by improving the transition curvature. A method for constructing the write head includes forming a magnetic write pole by forming a mask structure over a deposited write pole material, the mask structure having an alumina hard mask and an image transfer layer such as DURAMIDE®. An alumina fill layer is then deposited and a chemical mechanical polish is performed to open up the image transfer layer. A reactive on etch is performed to remove the image transfer layer and a reactive ion mill or reactive ion etch is performed to remove the alumina hard mask and form a concave surface on the write pole.

摘要： A magnetic write head for perpendicular magnetic recording that has write pole, a return pole and a trailing shield that is magnetically connected with magnetic return pole. The write head includes a magnetic pedestal and first and second magnetic studs that connect the trailing shield with the pedestal. The studs are laterally spaced a distance that is not greater than 5 um from the nearest side of the write pole. In other words, the studs are spaced from each other a distance that is no greater than the width of the leading edge of the write pole plus 10 um. This spacing of the studs prevents saturation of the trailing shield, maximizing field gradient and ensuring optimal magnetic write performance.
