Abstract
A magnetic transducer head utilizing magnetoresistance effect having a circuit for applying a constant voltage to outer ends of at least one pair of magnetoresistance effect elements provided in series on a discontinuous portion other than a magnetic gap of a magnetic core forming a magnetic gap and a conductor arrangement for applying bias magnetic fields opposite in polarity to the magnetoresistance effect elements, respectively wherein an output is derived from a connected point between the pair of magnetoresistance effect elements.
