ABSTRACT:
A magnetic head for reading analogue information on a track of a recording medium associated with the magnetic head. The head has a strip of magnetoresistive material serving as a reading element and arranged in a magnetic yoke at a given distance from the pole faces formed by the ends of the limbs of the magnetic yoke, the strip being connected in the magnetic circuit formed by the magnetic yoke. The magnetic yoke comprises three limbs separated by non-magnetic layers. The pole face of one of the outer limbs is located at a greater distance from the recording medium than the pole faces of the central limb and the other outer limb.
