Patent ID: 7881012

Claim:
A magnetic head for a perpendicular recording comprising a main pole and an auxiliary pole, wherein the main pole has a track-width determining air bearing surface; the main pole comprises a yoke part and a pole tip; the pole tip providing the air bearing surface and the yoke part is recessed from the air bearing surface in a direction perpendicular to the air bearing surface; the pole tip comprises a first magnetic film and a second magnetic film; the first magnetic film is coupled to the yoke part and has, at the air bearing surface, a first width; the second magnetic film is coupled to the first magnetic film and has, at the air bearing surface, a second width; the second width is greater than the first width; the first magnetic film has a first throat height extending perpendicular from the air bearing surface for a first distance; the second magnetic film has a second throat height extending perpendicular from the air bearing surface for a second distance; and the second distance is smaller than the first distance.
