    摘要： A method of manufacture of magnetic heads which include CoFe elements using CMP is presented. The method includes providing a slurry of Al2O3, adjusting the concentration of H2O2 in said slurry to within a range of 6-12% by volume and balancing mechanical polishing action. The balancing is done by adjusting the table speed of a mechanical polisher to within a range of 55-90 rpm, and adjusting polishing pressure to within a range of 5-7 psi. Also a magnetic head having elements made of CoFe material made by this method is disclosed.

    摘要： A method for fabrication of magnetic write heads for disk drives in which a P1 layer is formed having a P1 Protrusion, the P1 Protrusion having a longitudinal reference axis. A gap layer is deposited on the P1 Protrusion and a layer of fill material is deposited on the gap layer. The fill material layer is shaped to form a mold which surrounds a hollow which is aligned with the longitudinal axis of the P1 Protrusion. This hollow in the fill material layer is filled with P2 pole material to form a P2 pole which is then automatically substantially aligned with the longitudinal axis of the P1 Protrusion.
