摘要： An inductive write element for use with a magnetic data recording and retrieval system is provided. The write element includes a magnetic yoke having an electrically conductive coil passing there through. The yoke is constructed of first and second magnetic poles, and performance of the write element is improved by the inclusion of a very thin pedestal of a high magnetic moment material on the first pole in the pole tip region. Further performance gains are realized by providing a tapered edge on the pedestal to facilitate magnetic flux flow through the pedestal.

摘要： A method and system for fabricating a perpendicular magnetic recording head, and the head so formed, are described. The method includes depositing an underlayer directly on an insulating layer. The underlayer preferably includes at least one of a nonferromagnetic metal, silicon oxide, and silicon nitride. A pole layer, which has a pole removal rate, is provided on the underlayer. The method and system further include forming a perpendicular magnetic recording pole from the pole layer. The perpendicular magnetic recording pole has a top and a bottom that is narrower than the top. The process of forming the perpendicular magnetic recording pole further includes removing a portion of the pole layer such that a pole removal rate for the pole layer is less than or substantially equal to a removal rate of the underlayer during the removing step.

摘要： Embodiments in accordance with the thin film write head of the present invention have a lower pole structure, an upper pole structure, and a multilayer write gap extending from an air bearing surface between the upper and lower pole structures. In preferred embodiments, the write gap comprises at least two of: (a) a first layer covering a lower pole tip portion of the lower pole structure, (b) a second layer covering turns of a semiconductor winding, or (c) a third layer covering a winding insulation stack. In more preferred embodiments, the write gap is formed of the first, the second, and the third write gap layers. An advantage of a write head with a multilayer write gap is that it allows better control of write gap thickness. As such, loss of write gap thickness can be compensated for by deposition of the second write gap layers, or by deposition of the third write gap layer. Some embodiments have one or more additional advantages in providing increased corrosion prevention, improving the integrity of conductor insulation, and/or improving the top pole magnetic material characteristics.

摘要翻译： 根据本发明的薄膜写入头的实施例具有从上和下极结构之间的空气轴承表面延伸的下极结构，上极结构和多层写入间隙。 在优选实施例中，写入间隙包括以下中的至少两个：（a）覆盖下极结构的下极尖端部分的第一层，（b）覆盖半导体绕组的匝的第二层，或（c） 覆盖绕组绝缘堆叠的层。 在更优选的实施例中，写入间隙由第一，第二和第三写入间隙层形成。 具有多层写入间隙的写入头的优点在于它可以更好地控制写入间隙厚度。 因此，可以通过沉积第二写间隙层或通过沉积第三写间隙层来补偿写间隙厚度的损失。 一些实施例在提供增加的防腐蚀性能，改善导体绝缘的完整性和/或改善顶极磁性材料特性方面具有一个或多个附加优点。

摘要： A thin film read/write head with a high performance inductive write section that incorporates a single layer coil with an improved fabrication method of a center tab of the single layer coil. The center tab is formed before the main body of the single layer coil is formed. Several advantages can thus be achieved. The coil resistance and inductance can be monitored for all the devices immediately after the coil fabrication to improve yield by identifying additional processing or rework before final production. Several conventional wafer processing steps can be eliminated, thereby shortening the cycle time of wafer processing. The chance of corrosion or delamination of the second pole P2 is significantly reduced.
