磁気ヘツド。[Claims for Utility Model Registration] A magnetic head that performs perpendicular magnetization recording on a magnetic recording medium having an axis of easy magnetization in the perpendicular direction, the main magnetic pole facing the magnetic recording medium and performing recording and reproduction, and the magnetic recording medium. one or more auxiliary magnetic poles that face the magnetic flux and form a return path for the magnetic flux, and are connected to the magnetic recording medium via an intermediate portion that forms a gap that is sufficiently larger than the gap between both magnetic poles and the magnetic recording medium. The area of the surface of the auxiliary magnetic pole facing the magnetic recording medium and the length of the surface facing the magnetic recording medium in the direction along the moving direction of the magnetic recording medium are the area of the surface of the main magnetic pole facing the magnetic recording medium and the length of the surface facing the magnetic recording medium along the moving direction of the magnetic recording medium is sufficiently large, and the edge of the surface of the auxiliary magnetic pole facing the magnetic recording medium is rounded; Further, the length of the main magnetic pole and the auxiliary magnetic pole in the magnetic recording medium running direction from the magnetic recording medium facing surface to at least the intermediate portion of the two magnetic poles is the same as the length of the main magnetic pole and the auxiliary magnetic pole in the magnetic recording medium running direction on the magnetic recording medium facing surface. A magnetic head characterized by being no shorter than its length.
