PROBLEM TO BE SOLVED: To attain the generation of a sufficient head generating magnetic held in a surface recording density of several tans to several hundreds giga-bit/ in2 or larger by concentrating the magnetic field to a single part of a main magnetic pole for reducing the change of intensity of the generating magnetic field which is the effect of the head generating magnetic field due to the arranging position of coils in a perpendicular magnetic head utilizing a thin film single magnetic pole. SOLUTION: The structure of the magnetic head for recording the information on magnetization onto the perpendicular magnetic recording medium is constituted in such a manner that a magnetic yoke magnetically combined with the main magnetic pole and the recording coils intersected with a magnetic circuit formed by the main magnetic pole and the above magnetic yoke are furnished, and the main magnetic pole has the wider part on the rear side than the width confronted with the perpendicular recording medium surface so that the recording coils are intersected at an optional position between the wider part of the main magnetic pole and the magnetic yoke.
