Magnetic reading device with read head matrix network |
摘要 |
A magnetic reading device, of the type comprising multiple magnetic read heads, incorporates read heads each formed by a magneto-resistance element having a resistance which varies as a function of an outside magnetic field. The magnetic reading device comprises a network of line conductors intersected with a network of column conductors to form intersections at which a read head is provided. The first and second ends of each magneto-resistance element forming the read heads are respectively connected to a line conductor and to a column conductor of the corresponding intersection, and a control voltage is applied to the line and column conductors by a switching element for each line conductor, column conductors being connected to a current sensor. A simplification of the control of read heads results from this arrangement, while avoiding the effect of the heads not selected on the variations of current coming from the selected heads.
