PURPOSE:To prevent wear and damage of the surface of a magnetic recording medium and to lower the cost of head, by pressing and sliding a slider consisting of perforated ceramic on a wrap dish made of soft material and solidifying and filling the soft material in the pore on the ceramic surface. CONSTITUTION:In the manufacture of floating type magnetic head providing a magnetic core 2 to a slider supported with a plate spring 3 retained with an arm 4, for example, the slider 1 is made of perforated ceramic such as barium titanate. To avoid damaged recording medium 6 with the pore 5 on the surface of the slider 1 and invasion of shaped recording medium and dust into the pore 5, after coating wrap liquid and abrasive particles on Sn-made-wrap dish the surface of which is formed as pear-skin, for example, the surface of the slider 1 is pressed and slided to solidify the Sn in the pore 5 and the slider 1 surface is wrapped to form smooth surface. Graphite and Teflon is used in place of Sn. |
