A magnetic head utilizing the magneto-resistive effect with at least two magneto-resistive elements present in one plane at right angles to the recording medium. The elements are connected to an output circuit in which their signals are subtracted from each other. In this manner compensation is provided for both interference signals and crosstalk signals. The head may comprise a reading element and a compensation element arranged above it or a reading element flanked by two compensation elements with a larger distance to the recording medium or with a smaller height.
