摘要： Methods for fabrication of tapered magnetic poles with a non-magnetic front bump layer. A magnetic pole may have a tapered surface at or near an air bearing surface (ABS), wherein a thickness of the write pole increases in a direction away from the ABS. A non-magnetic front bump layer may be formed on the tapered surface of the magnetic pole and away from the ABS. The front bump layer may increase the separation distance between a shield layer and the magnetic pole near the tapered surface, thereby improving the performance of the write head.

摘要： A perpendicular magnetic recording write head has a main pole and return poles that are substantially coplanar. The write head includes a main pole, two return poles and a connecting stud that are all formed as a single layer in a single deposition and patterning step. The coplanar main and return poles lie in a plane parallel to the cross-track direction. The two return poles are thus spaced from the main pole in the cross-track direction. The main pole includes a write pole connected to it but lying in a plane spaced in the along-the-track direction from the plane of the main pole. The write head includes a helical coil wrapped around the main pole. The magnetic flux path is from the write pole to the disk recording layer in a data track aligned with the write pole, to the disk underlayer beneath the recording layer, through the underlayer to data tracks spaced cross-track from the data track aligned with the write pole, and back through the return poles.

摘要： A double notched magnetic structure for use in a magnetic head for avoiding stray field writing. The structure could be a magnetic shield, magnetic pole of a write head or some other magnetic structure used in a magnetic head of a magnetic recording system, and has notches formed at both the front end (adjacent to the ABS) and at the back end (away from the ABS). The notches at the front end form a forward protruding portions that performs the necessary function of the structure, such as magnetic shielding, and has laterally extending recessed portions (recessed by the front notches) that move the flux focal points of the structure away from the ABS to avoid stray field writing. The back notches form a backward extending portion that affects the geometry of the structure to prevent the focusing of magnetic flux caused by stray magnetic fields having a component perpendicular to the ABS.

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 independently controlling track width and bevel angle of a write pole tip having a P3 pole tip for perpendicular recording. The method includes establishing the track width in a portion of the P3 layer material. A portion of this portion having the established track width is protected by providing a temporary masking material to make a protected portion. At least one unprotected portion is left exposed to be shaped. This unprotected portion is then beveled to produce at least one beveled portion having a bevel angle. The protected portion produces a rectangular portion which together with the beveled portion produce a hexagonal pole tip. Also a magnetic head having a hexagonal pole tip, and a disk drive having a magnetic head having a hexagonal pole tip.

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 data recording having a write pole that is sandwiched between first and second magnetic shaping layers. The split shaping layers allow a laminated shaping layer structure allows a manufacturable laminated shaping layer to be constructed for improved data rate. One of the magnetic shaping layers can be formed as a laminated structure while that other can be a single layer of electroplated magnetic material. The shaping layers can be separated from the write pole by a thin layer of non-magnetic material to form a laminated interface between the write pole and the shaping layers. These features reduce magnetic domains and also reduce eddy currents which advantageously improves data rate.

摘要： In a perpendicular recording head, a notch is formed in the top write gap at a location on top of the main pole. A perpendicular head with this notched top write gap structure has less transition curvature and better writability while reducing the adjacent track interference (ATI). Also, the process used to fabricate the head ensures that the trailing edge (writing edge) of the main pole is extremely flat with no corner rounding.
