ABSTRACT:
A magnetoresistance transducer for reading data from the tracks of a record carrier comprises at least one magnetoresistance perpendicular to the direction of travel of the data of each track P. First and second plane magnetic means are situated at either side of the magnetoresistance in such manner as to intercept and deflect the magnetic field lines transmitted by the immediate surroundings of the track P and by the data items adjacent to the data item which has the magnetoresistance positioned opposite to it.
