A perpendicular magnetic write head includes: a magnetic pole having an end surface exposed on an air bearing surface, and extending in a height direction perpendicular to the air bearing surface; a first yoke having an end surface exposed on the air bearing surface, and facing a forward section of the magnetic pole with a gap layer in between; a second yoke located behind the first yoke with an insulating layer in between in the height direction, and connected to a backward section of the magnetic pole; a shield connecting the first yoke to the second yoke; and an additional magnetic layer located behind a boundary between the first yoke and the insulating layer, and in contact with the first yoke. |
