A magnetic disc apparatus includes a double layered perpendicular
recording medium including a soft magnetic underlayer and a perpendicular
recording layer, which are formed on a substrate, and a perpendicular
magnetic recording head including a main pole generating a recording
magnetic field in a perpendicular direction, and an auxiliary pole
connected to the main pole on a trailing side to the main pole and having
a multilayered structure in which a nonmagnetic layer is sandwiched
between magnetic layers.
