Abstract: PURPOSE: To reduce the film strain while maintaining the conventional intensity of leaking magnetic field and to substantially prevent film peeling by forming a magnetic metallic film to the mid-way of the sloped part of a winding window from the part of the medium sliding surface. CONSTITUTION: This magnetic head is a metal-in-gap magnetic head 16 which has the magnetic metallic films 13 of a high saturation magnetic flux density of, for example, 'SENDUST (R)', etc., on the surfaces opposite to the magnetic gap of magnetic cores, for example, ferrite cores 12 and has the magnetic gap (g) formed between these magnetic films 13. The magnetic metallic films 13 are formed in the mid-way of the sloped parts 14a of the winding window from the part of the medium sliding surface 15, for which a joining material 17, such as solder glass, is used.  The magnetic metallic films 13 of this magnetic head 16 are parted and the length L from the surfaces opposite to the magnetic gap to the sloped parts 14a of the winding window is made short to the irreducible min., thereby, the intensity of the leakage magnetic fields, i.e., recording magnetic fields, equal to the intensity obtd. before is obtd. and simultaneously, the film strains of the magnetic metallic films 13 are decreased and the film peeling is subsequentially prevented. The reliability of the metal-in-gap magnetic head 16 of this kind is thus improved.
