摘要： A disk drive thin-film write head has a first ferromagnetic pole tip that includes a pedestal pole layer and a capping layer on the pedestal pole layer. A substantial portion of the pedestal pole layer is formed of a lower-moment alloy and the capping layer is formed of a higher-moment alloy and is made thick enough to compensate for the lower-moment alloy in the pedestal pole layer. The pedestal pole layer may be a bilayer of two different NiFe alloys with the upper layer in the bilayer having a higher moment, and the capping layer may be a CoFe alloy. The width of the pedestal pole layer is substantially reduced to reduce the pole tip area exposed. The reduced pole tip area and the increased use of lower-moment alloys enable a thinner protective film to be used to protect the pole tips from corrosion.
摘要翻译：磁盘驱动器薄膜写入头具有第一铁磁极尖，其包括底座极层和底座极层上的覆盖层。基座极层的主要部分由较小的力矩合金形成，并且覆盖层由更高的力矩合金形成，并且被制成足够厚以补偿底座极层中的较小的力矩合金。底座极层可以是两个不同的NiFe合金的双层，双层中的上层具有更高的力矩，并且覆盖层可以是CoFe合金。底座极层的宽度大大减小，以减小露出的极尖面积。减小的极端面积和增加使用较低的力矩合金使得可以使用更薄的保护膜来保护极尖免受腐蚀。

摘要： A magnetic head structure for use in perpendicular magnetic recording. The magnetic head includes a magnetic write head having a return pole with a magnetic shunt structure extending from the back end opposite the ABS. The magnetic shunt structure prevents magnetic field from the write coil from reaching and affecting the read head. More specifically the shunt structure prevents magnetic field from the portion of the write coil beyond the back gap (as measured from the ABS) from magnetizing a magnetic shield of the read head. The shunt structure is also configured so as to avoid stray field writing. The size and shape of the shunt structure is therefore, limited to avoid attracting stray fields that might cause such stray field writing.

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 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 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.
