ABSTRACT:
A slider being made of ferrite and a core formed with a magnetic metal film on its gap confronting surface are connected together by means of bonding glass so as to sandwich a non-magnetic film therebetween as a magnetic gap. The magnetic metal film is made of a magnetic metal material such as Fe-Ni, Fe-Al-Si and the like, and is constructed through the thin-film fabrication technology such as sputtering. A recessed portion is provided on the magnetic metal film in such a manner that the recessed portion is retracted from a medium confronting surface of the magnetic head by a depth t. Thus, no color change is caused on the magnetic metal material and, therefore, no deterioration in various characteristics of the magnetic head is expected.
