Abstract
PURPOSE:To minimize the dispersion of a gap depth by providing a step-formed level difference part at the upper part of the magnetic gap part of a magnetic head core chip, and processing it. CONSTITUTION:A coil groove 2, a level difference 3 for gap depth measuring and a reinforced glass filling groove 4 are provided on a first core 1, a gap forming surface 5 is finished as a mirror surface, a gap forming surface 5 of a second core 6 is also finished as the mirror surface, the spacer of a nonmagnetic material to specify the gap is stuck on both or either of the surfaces, and then, a magnetic head core block 7 is integrally obtained. A groove processing is executed so as to leave a track part with an arbitrary width on the block, a fusion glass 9 is fused, and a magnetic head core block 10 filled in a track groove is obtained. By cutting and polishing this, a magnetic head core chip is obtained. After the magnetic head core chip 11 is set to the inserting groove of a slider 12, and said fusion glass 9 is fused again and integrated, the level difference part 3 of the gap upper part can be seen from the upper part when a part of the upper part is polished. Thus, the gap width can be obtained simply and with the arbitrary dimension.
