Abstract
PURPOSE:To remove the distortion of reinforcement glass and the sliding surface of a head due to a cutting work by heat-treating the reinforcement glass, provided on the sliding surface side of the magnetic head, at above a specified temperature. CONSTITUTION:A groove 4 is formed on the both side parts of an operating gap 2, and the reinforcement glass 6 for maintaining the mechanical strength of the operating gap 2 and a recording/reproducing track 5 is molded in this groove 4. The side surface of the head is cut by a microslicer, and at that time, the distortion is generated in the reinforcement glass 6, and the distortion is generated in a core 1 as well. Then, the reinforcement glass 6 is heat-treated from a head side surface at above 500 deg.C. Thus, the distortion of the reinforcement glass 6 can be removed, and the distortion of the sliding surface 8 of the head can be removed as well.
