A perpendicular magnetic recording apparatus has a discrete track media including a substrate and a soft magnetic layer and a perpendicular recording layer formed on the substrate, the perpendicular recording layer including guard bands magnetically separating recording tracks from one another on the surface thereof, and a magnetic head including a main pole, an auxiliary yoke, and a coil. The main pole is adapted to have a shape on the air bearing surface satisfying a condition that a length of a line segment which is formed by projecting a side of the main pole along a head traveling direction onto a straight line perpendicular to the head traveling direction is smaller than a width of each of the guard bands in the discrete track media even when the main pole is positioned on any recording track of the discrete track media.
