ネル消去型磁気ヘツド。 In a tunnel erase type magnetic head in which a slider is bonded with resin to both sides of a magnetic head core assembly having an erase gap on both sides of a recording/reproducing gap part, there is a gap between the air groove of the slider provided in the joining direction and the core assembly. A tunnel erasing magnetic head characterized in that the protrusion of the formed slider has a cross-sectional shape in which the width of the protrusion on the bottom side of the air groove is wider than the width of the protrusion surface on the outward side.
