Abstract
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.
