Abstract
Magnetic head for reading information from a magnetic registration medium. Comprises a magnetic yoke (3) having two limbs (3A, 3B) whose free ends constitute pole faces (3A1, 3B1) on either side of a read gap (7). A magnetoresistive element (15A, 15B) provided within the magnetic yoke at a distance from the pole faces is constituted by a layer of Bi provided on the magnetic intermediate yoke (13). Viewed in the longitudinal direction of the read gap, the layer of Bi extends on either side of this gap and at least during operation it is in a constant magnetic field directed transversely to the layer of Bi.
