Magnetic head for perpendicular magnetic recording
摘要:
A magnetic layer for writing incorporates: a pole layer having an end face located in a medium facing surface; and an upper yoke layer. A first magnetic layer for flux concentration is connected to the pole layer at a location away from the medium facing surface, and allows a magnetic flux corresponding to a magnetic field generated by a first coil to pass. A second magnetic layer for flux concentration is connected to the upper yoke layer at a location away from the medium facing surface, and allows a magnetic flux corresponding to a magnetic field generated by a second coil to pass. When seen in the direction orthogonal to the interface between the second magnetic layer and the upper yoke layer, this interface is disposed at a location that does not coincide with the interface between the first magnetic layer and the pole layer.
