Patent ID: 7983001

Claim:
A magnetic head comprising a slider and a perpendicular recording head, wherein said perpendicular recording head includes a main magnetic pole film for emitting a perpendicular magnetic field and is supported by said slider, said main magnetic pole film includes an electrode film and a plated magnetic film and is disposed within a recess formed in a first non-magnetic film, said electrode film includes a Ru film and a conductive magnetic film, said Ru film is adhered to an inner wall surface of said recess or a surface of a second non-magnetic film adhered thereto, thereby following a shape of said inner wall surface of said recess, said conductive magnetic film is adhered to a surface of said Ru film, thereby following the shape of said inner wall surface of said recess, and said plated magnetic film is disposed adjacent said conductive magnetic film, thereby filling up said recess, wherein said Ru film has a film thickness in the range of 0.75 nm to 5 nm and a crystal orientation (110).
