Abstract:
A multi-channel magnetic head having a head face which extends in a first direction and in a second direction transverse to the first direction, for scanning a record carrier which is relatively movable with respect to the magnetic head in the first direction,comprising a structure of layers which extend respectively substantially in the second direction and in a third direction transverse to the first and second directions, said layers being disposed one on top of the other as viewed in the first direction, said structure including a plurality of magnetoresistive sensors, each of said magnetoresistive sensors comprising a magnetoresistive measuring element, a first magnetic element and a second magnetic element respectively, said magnetoresistive measuring elements being arranged such that, viewed in the second direction, adjacent magnetoresistive sensors are distinguishable; and, viewed in the first direction, the magnetic elements are opposite each other, at least the respective first magnetic elements extending as far as the head face, characterized in that both magnetic elements of each of at least two adjacent magnetoresistive sensors are electrically conducting and have respective electric connection faces, the respective magnetoresistive measuring element being electrically arranged in series between the respective two magnetic elements for passing a measuring current through the measuring element substantially in the third direction.
