成したことを特徴とする磁気ヘツド。[Claims for Utility Model Registration] A core chip that integrates a pair of cores in which thin laminate layers made by alternately laminating metal magnetic films and insulating thin films with high saturation magnetic flux density are sandwiched from both sides by non-magnetic plates. In this magnetic head, a metal magnetic film having a high saturation magnetic flux density is formed on the outer surface of the core chip except for the sliding contact surface with the magnetic recording medium and the area near the top adjacent to the sliding contact surface. Features a magnetic head.
