Abstract

PURPOSE:To obtain a magnetic head which is extremely easily produceable and maintains high wear resistance during the contact with a recording medium by forming a projecting part by a groove, packing high melting glass into the groove and forming a thin amorphous magnetic film and thin non-magnetic film then binding two base materials for a head chip by low melting adhesive glass or org. adhesive agent. CONSTITUTION:The projecting part 13 having the width coinciding with a track width B is formed by the groove 14 to cores 11, 12 consisting of ferrite. The high melting glass 15 is packed into the groove 14 and a thin amorphous magnetic film 17 is formed on the peak surface 16 of the projecting part 13. The thin non-magnetic film 18 having the thickness larger than the thickness of the film 17 is formed on the surface of the glass 15. The films 18 are then brought into contact with each other and the cores 11, 12 are bound by the low melting glass 19. A gap 20 is formed between the thin films 17 when the cores are bound in the above-mentioned manner.

Effects of the Invention As described above, the present invention forms a plurality of grooves, leaving a protrusion with a width matching the track width or a protrusion forming a gap with a width matching the track width, and forming a plurality of grooves with these grooves and gaps. Since the base material is filled with high melting point glass in advance, even if the base material is heated to a high temperature, an amorphous magnetic thin film that deteriorates at that temperature has not yet been formed, so there is no risk of deterioration. Since the magnetic thin film can be formed after the high melting point glass is formed, it is extremely easy to manufacture and it is easy to obtain a magnetic head with high wear resistance when in contact with a recording medium.
