Abstract
In a thin film magnetic head, a face surface faces a recording medium and a front surface of an upper core layer is a curved surface which gradually retreats in a height direction generally perpendicular to the face surface as it approaches both sides thereof, and the thickness of the upper core layer gradually increases in the height direction. It is thus possible to appropriately suppress the occurrence of side fringing, efficiently cause a magnetic flux to flow from the upper core layer to an upper pole layer, and make the thin film magnetic head adaptable to a higher recording density.
