Abstract
PURPOSE:To manufacture an efficient magnetic head by applying etching to a face opposing to a gap made of an oxide magnetic material by means of sputtering etching method to remove the work-affected layer of the oxide mag netic material. CONSTITUTION:An outer winding slot 12 and an inner winding slot 13 are formed on an oxide magnetic material block 11. Then the gap opposed face 14 is specularly polished. Then in order to obtain a prescribed track width a slot 15 is formed. Then 1-5mum of etching is applied by the sputtering etching method. Thus, the corner of the part 16 between the track slots 15 is much etched more than the other parts and a shape having a curvature at the tip is attained. An alloy magnetic material 17 is formed on the gap opposed face 14 by sputtering or the like. Then the nonmagnetic material such as SiO2 is formed on the gap opposed face 14 as a gap member by means of the sputtering and two blocks are butted and heated for bonding. This method is excellent in productivity because the sputtering method is employed.
