Abstract:
A current perpendicular-to-the-plane magnetoresistance (CPP-MR) read head, comprising:a top shield formed of magnetically shielding, electrically-conductive material; a bottom shield formed of magnetically shielding, electrically-conductive material; a multilayer magnetoresistance (MR) structure disposed between the top shield and the bottom shield, the MR structure being in electrical contact with the top and bottom shields; and a transverse magnetic field generating structure provided adjacent the MR structure in a direction to apply a transverse magnetic biasing field to the MR structure, the direction being perpendicular to a direction along which the MR structure is layered and parallel to an air bearing surface (ABS), wherein the transverse magnetic field generating structure includes a permanent magnet, and wherein the transverse magnetic field generating structure further includes a soft magnetic layer in magnetic contact with the permanent magnet.
