Multitrack magnetic head (1) comprising a substrate (9) on which a number of elongated magneto-resistive elements (3) are provided, which viewed in the longitudinal direction of the magneto-resistive elements are arranged at a distance from each other. The magneto-resistive elements are incorporated in a magnetic circuit constituted by a magnetic yoke (5, 7, 9) which is provided with pole faces (19, 21) for the purpose of co-operating with the registration medium, whilst each magneto-resistive element is provided with two contacts (3A) for connection to a measuring current source. To improve the stability of the magneto-resistive elements, the magnetic head has strip-shaped means (17) which magnetically couple the magneto-resistive elements and keep them electrically separated from each other.
