The perpendicular magnetic head is capable of solving the problems of side track erasing and pole erasing. The perpendicular magnetic head of the present invention comprises a write-head, which includes a main magnetic pole emitting magnetic fluxes toward a recording medium. An end face of a pole end is formed into a T-shape. A longitudinal pole section of the pole end is made of a low Bs magnetic thin film, whose end face is formed into a rectangle. A transverse pole section of the pole end is made of a high Bs magnetic thin film, whose end face is formed into a rectangle. The low Bs magnetic thin film and the high Bs magnetic thin film are determined by the formula: (area of the end face of the low Bs magnetic thin film)×(saturation magnetic flux density of the low Bs magnetic thin film)>(area of the end face of the high Bs magnetic thin film)×(saturation magnetic flux density of the high Bs magnetic thin film).
