Abstract:
A method of fabricating a magnetic write transducer on a base layer, the method comprising:forming a bottom pole overlaying the base layer; forming a write gap layer overlaying the bottom pole; forming a coil overlaying the write gap layer; forming an insulating layer overlaying the coil; depositing a top pole inner layer comprised of a first magnetic material overlaying the insulating layer and the write gap layer; forming a top pole outer layer comprised of a second magnetic material overlaying the top pole inner layer, wherein forming the top pole outer layer includes forming a plating mask overlaying the top pole inner layer; plating the top pole outer layer onto the top pole inner layer through the plating mask using the top pole inner layer as an electrically conductive path for carrying a plating current; and patterning the top pole inner layer using the top pole outer layer as a mask.
