Recording and reproducing magnetic head with magnetoresistant element compensated with respect to recording.

摘要

According to the invention, the head includes, under a magnetoresistant element (MR), a conductive element (40), and, preferably, an additional magnetic layer (44) punched with an opening (46). The conductive element (40) is in series with the write coil and connected up in such a way that, in the magnetoresistant element, the magnetic field resulting from the passage of the current through the conductive element opposes the write leakage field. Application to the magnetic recording of information. <IMAGE>
