Patent ID: 7933094

Claim:
A magnetic head for perpendicular magnetic recording comprising: a medium facing surface that faces toward a recording medium; a coil for generating a magnetic field corresponding to data to be written on the recording medium; a pole layer having an end face located in the medium facing surface, the pole layer allowing a magnetic flux corresponding to the magnetic field generated by the coil to pass therethrough and generating a write magnetic field for writing the data on the recording medium by means of a perpendicular magnetic recording system; a shield made of a magnetic material; and a gap layer made of a nonmagnetic material, wherein: the shield includes: a first layer having an end face located in the medium facing surface at a position forward of the end face of the pole layer along a direction of travel of the recording medium; and a second layer disposed between at least part of the coil and the medium facing surface and magnetically connected to the first layer; the second layer has an end face that faces toward to the medium facing surface, the end face being located at a distance from the medium facing surface; and the gap layer is disposed between the pole layer and the first layer, the magnetic head further comprising: a nonmagnetic layer made of an inorganic insulating material and disposed between the end face of the second layer and the medium facing surface; and a photoresist layer disposed between the end face of the second layer and the nonmagnetic layer.
