Patent number: 8837084Abstract: A magnetic write head having a stitched magnetic pole (also referred to as a shaping layer) for conducting magnetic flux to the pole tip portion of a magnetic write pole. The stitched magnetic pole has a shape so as to be thicker in a central region that is aligned with the pole tip of the write pole and is thinner a its outer sides. This shape helps to channel magnetic flux to the pole tip portion of the write pole while maintaining sufficient pole surface area for high data rate recording.Type: GrantFiled: November 29, 2012Date of Patent: September 16, 2014Assignee: HGST Netherlands B.V.Inventors: Wen-Chien D. Hsiao, Aron Pentek, Katalin Pentek, Junsheng Yang

Publication number: 20130020204Abstract: 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.Type: ApplicationFiled: July 20, 2011Publication date: January 24, 2013Inventors: Donald G.
