1508892 Magnetoresistive transducers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 March 1975 [1 April 1974] 12922/75 Heading G5R A head 1 for playback from a magnetic record 2 includes an elongate anisotropic magnetoresistive element 3 in which the current between end contacts 4, 5 is forced by one or more oblique readily electrically conductive (e.g. gold) equipotential strips 8 to flow at an angle (e.g. 45 degrees) to the easy direction of magnetization which is parallel to the longitudinal axis of the element 3. A magnet (not shown) generates a longitudinal auxiliary magnetic field H h having a strength of the same order as the coercive field strength of the element 3.
