ABSTRACT:
A magnetic reading device having two electrically series-arranged magnetoresistive elements, in particular for interference compensation and positioning control. A pattern of equipotential strips is provided on each element to adjust the quiescent angle .alpha. between the direction of magnetisation and the direction of current passage of one element between 30.degree. and 60.degree. and between 210.degree. and 240.degree., respectively, and that of the other element at 360.degree. - .alpha. and 180.degree. - .alpha., respectively, the device has for various applications an automatic compensation of the signals across the elements so that the use of difference amplifiers is superfluous. In addition, due to this adjustment, the reproduction characteristics has a linear variation.
