Abstract
An improved magnetic head comprises a slider and a thin film element, the later of which is provided on a trailing side of the slider. The slider has core layers. The surfaces of the core layers are abraded so that the thickness of an a phase constituting the surface structures of the core layers may be reduced to a very small value. In this way, even if a carbon film is directly formed on the core layers, it is still possible to ensure a desired diffusion between the carbon film and the a phase, thereby effectively preventing the carbon film from separation (peeling) and avoiding the formation of any spot on the carbon film.
