A nonmagnetic shunt layer is often deposited on the magnetoresistive layer of a magnetoresistive tape head as more f described in U.S.P. 3,967,368 to Shelledy, et al. Titanium is one of the preferred materials for this shunt layer as it has the desirable resistivity and etching properties. However, it has been found that the titanium is prone to interdiffuse into a subsequently deposited Nickel-Iron layer which requires that an oxide layer be formed on the surface of the titanium.
