Abstract:
1. A magnetic write head for perpendicular magnetic recording, comprising: A magnetic write pole, the magnetic write pole having first and second sides and a trailing edge surface that extends from the first side to the second side, and having a pole tip portion that extends to an air bearing surface and a flared portion removed from the air bearing surface, the flared portion and the pole tip portion meeting at a junction that defines a flare point; first and second magnetic structures extending from the first and second sides of the write pole, the magnetic structures each having a front edge that defines a secondary flare point located between the flare point and the air bearing surface, the first and second magnetic structure being formed so as not to contact the trailing edge surface of the write pole; and first and second non-magnetic spacer layers contacting the first and second magnetic structures, each of the non-magnetic spacer layers having a front edge that is aligned with the front edge of the magnetic structures.
