摘要： A magnetic write head for perpendicular magnetic data recording having a trailing shield with a two step throat height. The trailing shield is formed over a non-magnetic bump that forms a notch in the leading edge of the trailing shield. This notch defines a first, smaller throat height closest to the write pole and a larger throat height away from the write pole. The smaller throat height near the write pole prevents excess magnetic flux from leaking to the write pole, thereby ensuring efficient strong write field. The larger trailing shield throat height away from the write pole prevents magnetic saturation oft the trailing shield and also greatly facilitates manufacturing avoiding problems related to variations and deviations in manufacturing processes used to define the trailing shield.

摘要： A method for manufacturing a write pole for a perpendicular magnetic write head. The method includes forming a mask structure over a full film layer of magnetic write pole material. A layer of hard mask material such as conformally deposited alumina is then deposited full film over the mask and write pole material. An ion mill, such as in an Ar or CHF3 chemistry is then used to preferentially remove horizontally disposed portions of the alumina layer (hard mask layer), thereby forming vertical hard mask walls at the sides of the mask structure. An ion mill is then used to form the write pole, with the alumna side walls providing excellent masking for forming well defined write pole edges. A relatively gentle clean up process can then be performed to remove the remaining mask material and side walls. The use of the alumina side walls eliminated the need to use an alumina hard mask that extends over the entire top of the write pole, Because of this, after forming the write pole, a relatively gentle clean up such as TMAH etch and NMP can be used to remove the remaining mask and alumina walls from the write pole.
摘要翻译：一种用于制造用于垂直磁写头的写极的方法。该方法包括在磁性写入磁极材料的全部薄膜层上形成掩模结构。然后将诸如保形沉积氧化铝的硬掩模材料层沉积在掩模上并写入极材料。然后使用诸如Ar或CHF 3化学中的离子磨机来优先除去氧化铝层（硬掩模层）的水平设置的部分，从而在掩模结构的侧面形成垂直的硬掩模壁。然后使用离子磨机形成写柱，校准侧壁为形成良好定义的写极边缘提供了优异的掩模。然后可以执行相对温和的清理过程以除去剩余的掩模材料和侧壁。使用氧化铝侧壁消除了使用在写入极的整个顶部上延伸的氧化铝硬掩模的需要。因此，在形成写入极之后，可以进行相对温和的清洁，例如TMAH蚀刻和NMP可以用于从写入极上去除剩余的掩模和氧化铝壁。

摘要： A method for manufacturing a magnetic head for magnetic data recording, that allows a lapping termination point to be easily and accurately determined during lapping. The method includes constructing a lapping guide that has an electrically is formed to provide an abrupt change in resistance at a point where lapping should be terminated. This point of abrupt resistance change is located relative to the flare point of the write pole that the distance between the flare point and the air bearing surface can be accurately maintained. This abrupt resistance change also makes it possible to monitor both a stripe height defining rough lapping and an angled kiss lapping process using a single measurement channel.

摘要： An apparatus for patterning a self-aligned coil using a damascene process is disclosed. Coil pockets are formed in a first insulation layer disposed over a first pole layer. A barrier/seed layer is deposited along walls of the coil pockets in the insulation layer. Copper is formed in the coil pockets and over the insulation layer. The copper is planarized down to the insulation layer. The self-aligned coil process packs more copper into the same coil pocket and relaxes the coil alignment tolerance. Protrusions are prevented because of the more efficient and uniform spacing of the coil to reduce heat buildup in the head during a write.

摘要： A magnetic write head having a vertically laminated back gap structure and method of making the same are disclosed. The magnetic head is formed with lower and upper pole pieces and a back gap structure which connects the lower and the upper pole pieces in a back gap region. In one illustrative example, the back gap is a vertically laminated structure having alternating layers of magnetic and non-magnetic materials. Each alternating layer is perpendicular to both the lower and the upper pole pieces. This vertically laminated structure significantly reduces the eddy currents in the back gap region at high operating frequencies as the layers are oriented in a direction parallel with the magnetic flux.
