ABSTRACT:
The present invention relates to a perpendicular recording magnetic head. A main magnetic pole film includes an electrode film and a plated magnetic film. The electrode film includes a Ru film and a conductive magnetic film, and the Ru film, which follows the shape of an inner wall surface of a recess formed in a first non-magnetic film, is adhered to the inner wall surface of the recess or a surface of a second non-magnetic film adhered thereto. The conductive magnetic film is adhered to a surface of the Ru film, thereby following the shape of the inner wall surface of the recess. The plated magnetic film is disposed adjacent the conductive magnetic film, thereby filling up the recess.
