ABSTRACT:
A magnetic head includes a pair of magnetic cores each having a convexly processed part, the convexly processed parts being disposed opposite to each other with a magnetic gap member inserted therebetween, and a pair of glass blocks disposed on both sides of the pair of magnetic cores, thereby coupling together the pair of magnetic cores. In the magnetic head, a metal magnetic film is formed on a projection end face of the convexly processed part in each of the pair of magnetic cores. A pair of notches regulating a track width are formed on a magnetic tape sliding face of the pair of magnetic cores by electric discharge machining so as to flank a butted part of the convexly processed parts of the pair of magnetic cores from both sides. Each of the notches has a shape such that an interface thereof is not positioned out of an edge of a recording pattern on a magnetic tape when the magnetic tape travels.
