According to one embodiment, a perpendicular magnetic recording apparatus includes a write head including a main pole, a return pole and an exciting coil, and a medium having a soft underlayer and a perpendicular recording layer on a substrate, in which the main pole has a length P in a down-track direction longer than a length T in a cross-track direction at a trailing edge, and has a leading edge recessed from a trailing edge on an air-bearing surface, and in which a gap G between the main pole and the return pole is smaller than twice a distance S between the air-bearing surface of the write head and a surface of the soft underlayer of the medium.
