Abstract

PURPOSE:To obtain a compound thin-film head which is aligned easily to centers of a recording track and a reproducing track, by using a transparent substrate as thin- film element formed one. CONSTITUTION:Both sides of a transparent or translucent substrate 17 made of glass, single-crystal or light-transmissive alumina, or the like are polished; after a lower magnetic film 8 is formed on one surface and an insulating film 11 for a gap in common and a conductive film 9 are further formed, an upper magnetic film 8' is formed and after a recording or reproduction side thin-film element 14 is formed, a protective film 12 is formed. On the other surface of the substrate 17, the other element 14 and protective film 12 for recording or reproduction are formed. Since the position relation between the thin-film elements where elements are already formed is confirmed through the transparent substrate 17, the thin-film element formed in the post process is arrayed with the accurate position relation with the opposite- side thin-film element formed in the prior process.
