Zusammenfassung:PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording head and a method of manufacturing the same. SOLUTION: The perpendicular magnetic head includes: a main pole; a coil enclosing the main pole as a solenoid type to allow the main pole to generate a magnetic field required for recording information on a recording medium; and a return yoke forming a magnetic path of a magnetic field together with the main pole and having a throat disposed opposite the main pole through a prescribed gap, wherein one end of the gap disposed near an ABS is thinner than the other end of the gap.
