Abstract
A method is provided for producing a magnetic head which includes a pair of magnetic cores. The method includes the steps of disposing projection end faces of respective magnetic cores to and opposite each other with a magnetic gap member inserted therebetween. The magnetic cores are welded together with a pair of back glass blocks, and a pair of circular shaped notches regulating track width are formed via electric discharge machining. Thereafter, a groove is filled with a glass material using heat treatment to form front glass blocks interposed between a magnetic tape sliding face and the back glass blocks.
