ABSTRACT:
A magnetic head having a first core half body constituted by a first non-magnetic base and a magnetic layer made of a high-permeability magnetic material and formed on the first non-magnetic base, and a second core half body constituted by a second non-magnetic base and a magnetic layer made of a high-permeability magnetic material and formed on the second non-magnetic base. This magnetic head is provided with a track width regulation groove communicating with at least one of recording medium sliding surfaces of the first and second non-magnetic bases, the track width regulation groove being filled with the magnetic layer; and abutting surfaces formed on the sides of the track width regulation groove opposite to each other in the widthwise direction of the track, the abutting surfaces being parallel to the surface of mating one of the first and second core half bodies when the abutting surfaces abut there-against. The first and second core half bodies are connected to each other by at least a portion of the abutting surfaces.
