Abstract:
A perpendicular magnetic recording head which moves in a track direction of a recording layer of a perpendicular magnetic recording medium to write information on the recording layer or read information from the recording layer. The perpendicular magnetic recording head includes: the perpendicular magnetic recording medium including a soft magnetic underlayer and the recording layer; a write head including a main pole that applies a magnetic field to, and writes information to, the recording layer and a return pole having a first end which is connected to the main pole and having a second end which is spaced apart from the main pole over an air bearing surface (ABS) of the perpendicular magnetic recording head which is adjacent to the recording layer; and a permanent magnet formed on at least one side of the write head.
