摘要： A magnetic write head having a tapered trailing edge and having a magnetic layer formed over a trailing edge of the write pole at a location recessed from the ABS, the magnetic layer being separated from the trailing edge of the write pole by a thin non-magnetic layer. The thin non-magnetic layer is preferably sufficiently thin that the magnetic layer can function as a portion of the write pole in a region removed from the ABS. A trailing magnetic shield is formed over the write pole and is separated from the write pole by a non-magnetic trailing gap layer. A non-magnetic spacer layer can be formed over the magnetic layer to provide additional separation between the magnetic layer and the trailing magnetic shield.

摘要： A method for manufacturing a magnetic write head having a write pole with a tapered leading edge formed on a substrate having a tapered surface and a wrap-around, trailing magnetic shield. The method uses a multi-layer anti-reflective coating prior to formation of the shield so that reflection from the tapered surface of the substrate does not affect the lithography of the mask used to form the trailing shield. The multi-layer antireflective coating is constructed of materials that can be left in the finished head, thereby eliminating problems associated with removal of the anti-reflective coating.
摘要翻译：一种用于制造具有形成在具有锥形表面的基底上的锥形前缘的写入极和缠绕的磁性磁屏蔽的磁性写入头的制造方法。该方法在形成屏蔽之前使用多层抗反射涂层，使得来自衬底的锥形表面的反射不影响用于形成后屏蔽的掩模的光刻。多层抗反射涂层由可以留在成品头中的材料构成，从而消除与去除抗反射涂层有关的问题。
