摘要： A method for manufacturing a write head with a helical coil having a very small and well controlled spacing between adjacent coil leads. The method includes forming a first set of coil leads, then conformally depositing a thin layer of electrically insulating material such as alumina over the first set of coil leads and over the substrate. An electrically conductive seed layer is then deposited over the thin layer of non-magnetic, electrically insulating material An electrically conductive material such as Cu is then deposited by electroplating in order to form a second set of electrically conductive leads interspersed within the first set of electrically conductive leads, each of the second set of leads being separated from the second set of leads by a portion of the thin layer of non-magnetic, electrically insulating material.

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 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 structure for use in a magnetic head for avoiding stray field writing. The magnetic structure can be for example a magnetic shield or could be a magnetic pole of a write head and is particularly advantageous for use in a perpendicular recording system, because such perpendicular recording systems are especially susceptible to stray field writing. The magnetic structure includes a forward protruding portion that extends toward the air bearing surface (ABS) of the head also includes first and second wing portions that extend laterally from the forward protruding portion. The wing portions each have includes an inner constant recess portion, and an outer tapered portion. The inner constant recess portion of each wing prevents stray field writing while also preventing magnetic saturation, the outer tapered portions, which taper away from the ABS as they extend laterally outward, further prevent stray field writing by removing the outer corners of the shield away from the ABS.

摘要： A method for constructing a magnetic write head using an electrical lapping guide to carefully control critical dimensions dining a lapping operation used to define an air bearing surface. The lapping guide is photolithographically patterned in a common photolithographic step with another write head structure so that special relation between the lapping guide and critical dimensions of the write head structure can be carefully maintained. For example, the electrical lapping guide can be patterned in a common photolithographic step as the write pole so that the location of the flare point can he carefully controlled with respect to the location of the lapping guide. A stitched flare structure can also be built together with the electrical lapping guide, then a self-aligned shield can be further built over this stitched flare structure so that both flare point and shield throat can be controlled tightly together by this electrical lapping guide during lapping process. Similarly, the lapping guide can be formed in a common photolithographic step with a trailing shield, so that a critical dimension such as throat height of the trailing shield can be carefully controlled with respect to the electrical lapping guide.

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.
