description Embodiments of the invention provide a perpendicular magnetic head with a narrow track and excellent high frequency characteristics. In one embodiment, a recording magnetic head includes coil conductors and magnetic pole pieces putting the same therebetween, in which a main magnetic pole piece is formed into a planar structure and a magnetic film connected with the main magnetic pole piece in a magnetic coupling relation is curved in the direction of the film thickness. Further, a shield material disposed near the main magnetic pole piece is made of a material of higher resistance than that of the material for the read shield.
