Abstract
Magnetic read/write head having a writing-compensated magneto-resistant element. In the invention, the head includes, beneath a magnetoresistant element (MR), a conductor element (40) and preferably an additional magnetic layer (44) perforated by an opening (46). The conductor element (40) is in series with the writing coil and connected in such a way that, in the magnetoresistant element, the magnetic field resulting from the passage of the current in the conductor element opposes the writing leakage field.
