PURPOSE: To obtain a magnetic head having high thermal stability and saturated magnetic flux density, easy to be manufactured and having a high characteristic by a method wherein an amorphous magnetic alloy containing only a metal element substantially as a vitrifiable element, and moreover having a soft magnetic characteristic is adhered to be formed on a substrate according to the sputtering method.
CONSTITUTION: At least a part of a magnetic material is constructed of the sputtered film of an amorphously magnetic alloys containing only a metal element substantially as a vitrifiable element, and moreover having a soft magnetic characteristic. The above-mentioned vitrifiable element is made as one element or more out of Zr, Ti, Hf, for example, the above-mentioned amorphous alloy is made as one element or more out of Co, Ni, Fe, for example, or a transition-metal is added thereto moreover, and the above-mentioned vitrifiable element is contained. Because the magnetic head obtained in such a way has a high allowable heating temperature, a heating process at manufacture of the head is facilitated, the produced head has a magnetic characteristic suitable to be used for a recording medium of high coercive force, and corrosion resistance and abrasion resistance are also favorable. Moreover, because the sputtering method is used, reduction of yield due to oxidation of the material at manufacturing time is not generated.
