<p>The head includes a magnetic circuit with two magnetic concentrators (191,192), two pole pieces (221,222) separated by a non-magnetic space (24) and a MR element which is positioned underneath the non-magnetic space (24). The two concentrators are separated from the two pole pieces by a non-magnetic layer (30) which includes at least one metallic layer (34). The non-magnetic layer includes an insulating layer (32) which is covered by a metallic layer (34). The non-layer has a thickness which lies between a fraction of a micrometer and several micrometers.</p> |
