PROBLEM TO BE SOLVED: To prevent the occurrence of undesired diffusion and interlayers stripping after manufacturing in a heating device in a magnetic head. SOLUTION: The heating device 112 is manufactured with diffusion barrier layers 138, 148, 170 and/or adhesion layers 134, 152, 174 beneath the heating device layers, between heating device layers and/or the heating device layers. The diffusion barrier layers prevents the diffusion of the metal materials that comprises the heating device layers into layers that are disposed below and/or above the heating device. the adhesion layers promote adhesion of heating device to the magnetic head layers adjacent to the heating device. The diffusion barrier layer may be comprised of tantalun, tantalum nitride, other tantalum alloys, titanium, rhodium, and the adhesion layer may be composed of tantalum, tntalum nitride, tantalum oxide, other tantalum alloys, titanium, nickel iron, chromium, platinum alloys, nickel allopys, and aluminum oxide.
