Abstract
A metal-in-gap type magnetic head apparatus in which a pair of magnetic core half bodies, comprising a metallic magnetic film containing Fe as a main component on at least one magnetic core half body, are joined. In the above mentioned structure, at least a part of the surface of a supporting base of the magnetic head comprises a material having a lower standard electrode potential than the metallic magnetic film and thereby the metallic magnetic film has a high saturation flux density. Moreover, a magnetic head apparatus and magnetic recording apparatus of the present invention can have a high reliability even in the strong corrosive environment.
