摘要： A method and apparatus for integrating a stair notch and a gap bump at a pole tip in a write head is disclosed. A protective plated layer is formed over the bump to prevent the bump form being damaged during formation of the notch at the pole tip. The flux from the second pole outside of the track will be effectively channeled to the first pole piece under the alumina bump.

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 and method of manufacture thereof that has a first pole structure having a step notched first pole structure. The step notched structure includes a bottom notched portion that is wider than the second notched portion formed thereover. The upper, or narrower, notched portion has a width that is substantially equal to and self aligned with a second pole structure (P2) formed thereover. The invention may also include first and second wing portions formed in the first pole that are recessed from the ABS and that extend laterally from the first notched portions of the first pole. The formation of the winged portions is assisted by an ion mill resistant bump (alumina bump) formed thereover, which acts as a mask during the ion milling operations that are used to form the first and second notches.

摘要： The invention is a perpendicular magnetic recording write head with a write pole, a trapezoidal-shaped trailing shield notch, and a metal gap layer between the write pole and notch. The write pole has a trailing edge that has a width substantially defining the track width and that faces the front edge of the notch but is spaced from it by the gap layer. The write head is fabricated by a process than includes reactive ion beam etching of a thin mask film above the write pole to remove the mask film and widen the opening at the edges of the write pole. The gap layer and notch are deposited into the widened opening above the write pole. The write pole has nonmagnetic filler material, such as alumina, surrounding it except at its trailing edge, where it is in contact with the gap layer, which is formed of a different material than the surrounding filler material.

The magnetic shield has a trailing portion that is separated from the leading edge of the writ pole by a non-magnetic trailing gap, and has side shield portions that are separated from first and second side portions of the write pole by first and second non-magnetic side gaps. The magnetic shield can be configured with notches at either side of the trailing portion of magnetic shield. These notches can extend in the trailing direction by a distance that is preferably ¼ to 1 times the trailing gap thickness. The width of the straight, trailing portion of the shield is preferable ½ to 1 times of the main pole width.

摘要： A method for fabricating a magnetic head using a modified P1 cap process. A first pole is formed. A cap is formed above the first pole. A gap layer is formed above the cap. A second pole is formed above the gap layer. Exposed portions of the gap layer are removed. The cap and first pole are milled for creating a shoulder of the first pole tapered upwardly towards the cap. Another method for fabricating a magnetic head includes forming a first pole, forming a gap layer above the first pole, forming a second pole above the gap layer, forming a layer of photoresist above the second pole, patterning the photoresist such that the photoresist covers areas of the gap layer positioned towards the second pole, removing exposed portions of the gap layer, removing part of exposed portions of the first pole for forming steps in the first pole on opposite sides of the photoresist, removing the photoresist, and milling for creating a shoulder of the first pole tapering upwardly towards the cap.

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.
