Abstract
Abstract A magnetic circuit (P1, P2, P3), whose thickness is equal to the width of the track to be read, is formed on a silicon substrate (10). This magnetic circuit is broken by a non-magnetic spacer (20) and two slots (F1, F2) in which are inserted elements sensitive to the magnetic field, for example magnetoresistors. The latter are connected to a circuit (12) integrated into the silicon substrate. …<??>Application to the reading of data recorded on a magnetic track. …<IMAGE>…
