A magnetic head in which two magnetoresistive elements are disposed in parallel to patterns recorded on a magnetic recording medium and spaced apart from each other by a distance shorter than a minimum interval of the recorded patterns, the magnetoresistive elements being each disposed between adjacent ones of magnetic shields through an insulator. A magnetic recorded data readout device employs the magnetic head and generates an output proportional to a composite difference resistance obtained by differentially combining resistance variations of the two magnetoresistive elements. A device is provided for detecting the position of magnetization transition of the recorded pattern and the direction of relative movement of the magnetic head to the magnetic recording medium from the zero cross point, and the direction of inclination of the waveform of the output generated by the magnetic recorded data readout device.
