Abstract
A magnetic reading head having a magneto-resistive element of the non-magnetically biased type, in which the current is forced to flow through the element at an angle with the easy axis of magnetization. For adjusting the dynamic range of the element, the element is subjected to a variable strength auxiliary field having a direction of which is parallel to the easy axis of magnetization.
