    摘要: A method for forming a magnetic write head having a trailing shield with a tapered and stepped, self aligned trailing magnetic shield. The shield has a tapered portion that tapers away from the write pole as it extends away from the ABS. This tapered portion helps to channel flux to the pole tip portion of the shield, while preventing the loss of write field to the shield. The stepped portion of the shield further helps to prevent the loss of write field and also defines a secondary throat height of the shield that can be accurately located relative to the air bearing surface.

    摘要: A method for manufacturing a magnetic write head having a stepped trailing shield. The stepped trailing shield is formed by forming a non-magnetic bump over a write pole prior to electroplating a wrap-around magnetic shield. The method allows the location of the front edge of the bump relative to the back edge of the wrap-around shield to be monitored by measuring the electrical resistance of an electrical lapping guide formed concurrently with these features. This concurrent formation of a lapping guide can be used to define the relative location of other features as well, such as the location of a back edge of a wrap-around shield relative to a flare point of a write pole.

    摘要: A method for manufacturing a write pole for a perpendicular magnetic write head. The method employs a damascene process to construct the write pole with a very accurately controlled track width. The method includes depositing a layer of material that can be readily removed by reactive ion etching. This material can be referred to as a RIEable material. A mask is formed over the RIEable material and a reactive ion etching is performed to form a tapered trench in the RIEAble material. A CMP stop layer can the be deposited, and a write pole plated into the trench. A CMP can then be performed to define the trailing edge of the write pole. Another masking, etching and plating step can be performed to form a trailing, wrap-around magnetic shield.
