Method of plating using a polymeric barrier layer including a polyphenolic polymer which has a repeating unit of the formula: wherein R, R, R, R, and Rare individually hydrogen, a hydroxy group or an azo dye.

Plating using copolymer

A method of fabrication of the write head of a perpendicular recording head allows for production of Ppole tips of width less than 200 nm (200&#xd7;10meters). The method includes fabricating the Pflux shaping layer, depositing the Player, depositing a layer of ion-milling resistant material, depositing at least one sacrificial layer, shaping the Player into Ppole tip, removing the at least one sacrificial layer to leave the Ppole tip, and encapsulating the Ppole tip.

Ion mill process with sacrificial mask layer to fabricate pole tip for perpendicular recording

A method of manufacture of magnetic heads which include CoFe elements using CMP is presented. The method includes providing a slurry of AlO, adjusting the concentration of HOin said slurry to within a range of 6&#x2013;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&#x2013;90 rpm, and adjusting polishing pressure to within a range of 5&#x2013;7 psi. Also a magnetic head having elements made of CoFe material made by this method is disclosed.

CMP for corrosion-free CoFe elements for magnetic heads

A magnetic head having improved overwrite capabilities and reduced fringing fields are described along with methods of making the same. The magnetic head has a first pole piece and a second pole piece. The first pole piece includes a first bottom pole piece layer, a pedestal portion formed over the first bottom pole piece layer, and a notched top pole portion formed over the pedestal portion. A gap layer separates the second pole piece from the notched top pole portion. The pedestal portion has a first saturation magnetization Mand the top pole portion has a second saturation magnetization Mthat is greater than the first saturation magnetization M. The top pole portion has a substantially planar top surface over which a portion of the gap layer and the second pole piece are formed.
