Abstract

PURPOSE:To manufacture a holder at a low price and to cause the performance of a magnetic head to be stable by forming the holder with bending a non- magnetic substance, providing a plane to have step difference with the end face of a core chip and forming a slider to be composed of transparent resin on this upper surface. CONSTITUTION:Holders 18A and 18B are bent and formed by the thin film of the non-magnetic substance. At such a time, the head part of the holder 18A goes to be the plane which is lower than the upper surface of a core chip 1 only by step difference A. Next, the holders 18A and 18B are adhered to the core chip 1, covered with the transparent resin and ground and a slider 9 is formed. Thus, in a condition that the depth of gaps 2a and 3a can be easily controlled, resin 19A and 19B can be applied and ground. Then, the manufacture goes to be easy and the performance of the magnetic head is made stable.
