Abstract:
A perpendicular magnetic recording head including: a data recording module comprising a main pole, a return pole, and a coil wrapped around the main pole; and a data reproduction module including magnetic shield layers and a reading device located between the magnetic shield layers, wherein the width of a lower end of the main pole is gradually reduced in a downward direction thereof, and the lower end of the main pole comprises a first part and a second part extending from the first part, the first part having a curved surface of a first curvature and the second part having a curved surface of a second curvature. The first curvature can be equal to or different from the second curvature, and magnetic shield devices can be further disposed on both sides of the lower end of the main pole.
