Patent number: 7552523Abstract: A method and system for manufacturing a perpendicular magnetic recording transducer by a process that includes plating is described. The method and system include forming a chemical mechanical planarization (CMP) uniformity structure around a perpendicular magnetic recording pole. The CMP uniformity structure has a height substantially equal to a desired pole height. The method and system also include fabricating an insulator on the CMP uniformity structure and performing a CMP to remove a portion of the insulator. The CMP exposes a portion of the perpendicular magnetic recording pole and planarizes an exposed surface of the perpendicular magnetic recording transducer.Type: GrantFiled: July 1, 2005Date of Patent: June 30, 2009Assignee: Western Digital (Fremont), LLCInventors: Li He, Jun Liu, Danning Yang, Yining Hu

Patent number: 7554767Abstract: Methods are provided for fabricating an electrical lapping guide, and for using the electrical lapping guide to fabricate a transducer of a magnetic recording head. Additionally, transducers comprising an electrical lapping guide are also provided. Methods of fabricating the electrical lapping guide comprise forming a resistive element proximate to a shield pedestal. Accordingly, the resistive element is both aligned with the shield pedestal in a transverse direction, and closely spaced from the shield pedestal in a longitudinal direction. The resistance of the resistive element correlates well with a throat height of the shield pedestal, and the correlation is utilized in the methods of fabricating the transducer. When a magnetoresistive stripe is uses as a second electrical lapping guide while fabricating the transducer, the two can be used to control a tilt angle in the transverse direction during lapping.Type: GrantFiled: July 1, 2005Date of Patent: June 30, 2009Assignee: Western Digital (Fremont), LLCInventors: Yining Hu, Jun Liu, Yingjian Chen, Mark D.
