摘要： The present invention provides a thin film magnetic device realizing effective improvement in magnetic permeability in a high frequency area. The thin film magnetic device includes a thin film coil and a plurality of strip-shaped magnetic films disposed along a plane in which the thin film coil extends. The plurality of strip-shaped magnetic films are disposed to extend in one direction only in a pair of areas facing each other. The pair of areas is selected from four areas obtained by dividing, in the winding direction, the area where the thin film coil extends.

摘要： A method for fabricating a coil and pedestal for a write head using a common seed layer is described. A nonmetallic gap layer is deposited on a planarized pole piece surface. Openings for the pole piece pedestal and the back gap pole piece are etched through the nonmetallic gap layer. A seed layer comprising a magnetic material is deposited on the etched gap layer. Preferably the coil is fabricated first on the planar surface of the seed layer. The coil structure, the pedestal pole piece, back-gap pole piece, side and center tap connections are fabricated on the same seed layer. The remaining seed layer is removed, the coil is encapsulated, the wafer is refilled with alumina and the wafer is planarized. The prior art process can be resumed at this point. Optionally a second seed layer such as copper (Cu) can be used.

摘要： A method and apparatus using a pre-patterned seed layer for providing an aligned coil for an inductive head structure. The method uses an aligned process where the base plate imprint is fabricated on an electrically insulating layer and the reversed image is fabricated and etched into the coil insulation material, e.g., hard bake photoresist to alleviate the problems associated with complete ion removal of the seed layer between high aspect ratio coils. The method would also not be prone to plating non-uniformities (voids), and would not be subject to seed layer undercutting in a wet etch step process.

摘要： Magnetic heads having write coil structures with reduced electrical resistances for reducing thermal protrusion are disclosed. In one illustrative example, a magnetic head includes a magnetic yoke; a write gap layer formed between upper and lower poles of the magnetic yoke; and a write coil having a plurality of coil layers. Each coil layer of the write coil extends continuously between the upper and the lower poles through a plane defined by the write gap layer. Preferably, the write coil is formed using a damascene process, such that each coil layer is wider than each coil separating layer. Such a structure provides for a relatively large amount of coil materials to be used, which reduces the coil's electrical resistance. This, in turn, reduces the heat generated by the write coils during operation. Further, either one or both of the lower and upper poles may include a horizontally laminated structure of alternating magnetic and non-magnetic dielectric layers to further reduce heating caused by eddy current losses. Since thermal protrusion is reduced, the fly height of magnetic head may be made relatively small with a reduced risk of head-to-disk crashes and disk scratches.
摘要翻译：公开了具有降低的电阻以减少热突起的具有写入线圈结构的磁头。在一个说明性示例中，磁头包括磁轭; 形成在磁轭的上下极之间的写间隙层; 以及具有多个线圈层的写入线圈。写入线圈的每个线圈层通过由写入间隙层限定的平面在上极和下极之间连续延伸。优选地，使用镶嵌工艺形成写入线圈，使得每个线圈层比每个线圈分离层宽。这种结构提供了相对大量的待使用的线圈材料，这降低了线圈的电阻。这又减少了在操作期间由写入线圈产生的热量。此外，下极和上极中的一个或两个可以包括交替的磁和非磁性介电层的水平层叠结构，以进一步减少由涡流损耗引起的加热。由于热突起减少，所以磁头的飞行高度可以相对较小，同时降低了磁头与磁盘的碰撞和磁盘划痕的风险。

摘要： A magnetic write head for use in a data recording system having first and second magnetic pole, the first pole having a P1 pedestal. An electrically conductive coil passes through a space between the first and second poles for inducing a magnetic flux through the yoke formed by the first and second poles. A bi-layer insulation layer disposed between the poles includes a layer of photoresist for preventing voids and a layer of alumina formed thereover to provide a structural brace to prevent recession of the P1 pedestal during manufacturing operations such as soda blast.
