ABSTRACT:
As a protective film of an element and a slider in a magnetic head, a film is provided which is excellent in adhesiveness to a film forming surface and which shows sufficient corrosion-resistance property with a thinner thickness. To provided this film, according to the present invention, a DLC film as a protective film is formed onto an element portion end surface and a surface of a slider of a magnetic head core. A film deposition step is conducted plural times to obtain the DLC film with a predetermined thickness when the DLC film is formed using an electric discharge.
