Abstract
A magnetic head for detecting information-representing magnetic fields on a magnetic recording medium and comprising an elongate magneto-resistive element of a magnetically anisotropic material which at its ends has contacts for connection to a current or voltage source. In order to linearize the playback characteristic of the element, the easy axis of magnetization coincides with the longitudinal direction of the element and means are present which force the current to travel at an angle of minimum 15.degree. and maximum 75.degree. with the longitudinal direction. These means consist in particular of equipotential strips provided on the element.
