Abstract
A magnetic transducer head utilizing magnetoresistance effect is disclosed which includes a thin film magnetoresistance effect element held between, first and second substrates, at least one of the first and second substrates being formed of an electrically conductive material, and a biasing means for the magnetoresistance effect element to satisfy a potential relation V.sub.MR -V.sub.S .ltoreq.0.2 volt, wherein V.sub.MR is a potential of the magnetoresistance effect element, and V.sub.S is a potential of the conductive substrate.
