Abstract:
1. A perpendicular magnetic recording head comprising: an auxiliary pole layer; a main pole layer; and a coil layer for providing a recording magnetic field to the auxiliary pole layer and the main pole layer, a front end face of the auxiliary pole layer and a front end face of the main pole layer being exposed at an opposing face of the perpendicular magnetic recording head opposing a recording medium, the front end faces being separated by a gap therebetween, the coil layer being located inward from the opposing face, the perpendicular magnetic recording head writing magnetic data on the recording medium by a perpendicular magnetic field concentrated to the main pole layer, wherein the perpendicular magnetic recording head further comprises a nonmagnetic layer formed on the main pole layer and a connection layer extending from the auxiliary pole layer and being magnetically connected with the main pole layer, the connection layer being located inward from the opposing face, the coil layer surrounding the connection layer.
