Asymmetric type perpendicular magnetic recording head and method of manufacturing the same

摘要

An asymmetric perpendicular magnetic recording head and a method of manufacturing the same, wherein the perpendicular magnetic recording head includes a read head for reading data from a magnetic recording layer and a write head for writing data on the magnetic recording layer. A main pole of the write head has a first surface facing toward the inside of the magnetic recording layer, a second surface opposing a data recording surface of the magnetic recording layer, and a third surface facing toward the outside of the magnetic recording layer and the first surface is asymmetric to the third surface. An angle between one of the first and third surfaces and the second surface may be greater than 90°.
