Zusammenfassung:PROBLEM TO BE SOLVED: To prevent the deterioration of an MR film according to heat treatments of magnetic shielding films and magnetic poles of an MR heat or an MR induction type composite head having an MR head part for reproducing and an induction type head part for recording. SOLUTION: The magnetic poles and the magnetic shielding films comprises the soft magnetic thin films having the compsn. expressed by the formula (Fe1-x Mx )1-y Ny (M is at least one kind among Mg, Ca, Y, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn and B; x and y denote atomic ratios and are 0.01
