A perpendicular magnetic recording head includes: a main pole; a return pole spaced a predetermined gap from the main pole; an induction coil inducing a magnetic field on the main pole; and two or more gap shields, wherein the two or more gap shields are formed in the gap between the main pole and the return pole.
