ABSTRACT:
The read head according to the invention comprises a matrix network of elementary heads whose magnetic circuit comprises a magneto-resistive element. The different elements are electrically connected in columns and traversed by a current. Head selection lines enable the active line of heads to be selected. The read signal is collected on each column.
