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： Methods for fabrication of leading edge shields and tapered magnetic poles with a tapered leading edge are provided. The leading edge shield may be formed by utilizing a CMP stop layer. The CMP stop layer may aid in preventing over polishing of the magnetic material. For the tapered magnetic poles with a tapered leading edge, a magnetic material is deposited on a planarized surface, a patterned resist material is formed, and exposed magnetic material is etched to form at least one tapered surface of the magnetic material.

摘要： A method for manufacturing a magnetic write head having a tapered leading edge. The method includes depositing a sacrificial non-magnetic layer to a thickness that is at least as great as the thickness of the write pole to be formed. The sacrificial non-magnetic layer is then masked and ion milled so as to form a tapered edge on the sacrificial non-magnetic layer that extends through the thickness of the non-magnetic fill layer. A magnetic material is then deposited and planarized by chemical mechanical polishing. The remaining magnetic material forms the entirety of the magnetic write pole so that there is no need to deposit additional magnetic layers further construct the write pole.

摘要： A method for manufacturing a magnetic write head having a tapered write pole as well as a leading edge taper, and independent trailing and side magnetic shields. The method allows the write pole to be constructed by a dry process wherein the write pole material is either deposited by a process such as sputter deposition or electrically plated and the write pole shape is defined by masking and ion milling. The write pole has a stepped feature that can either be used to provide increased magnetic spacing between the trailing shield and the write pole at a location slightly recessed from the ABS or can be magnetic material that increases the effective thickness of the write pole at a location slightly recessed from the ABS. A bump structure can be further built over that stepped feature to enhance field gradient as well as reduce trailing shield saturation.
