ABSTRACT:
A magnetoresistive head achieves maximum signal output with minimal electromigration by use of two increased direct currents with different polarities which are directed periodically through a magnetoresistive element in opposite directions, with minimal long term directional diffusion for minimizing electromigration and for increasing the signal output. The magnetoresistive element defines two magnetic centers MC.sup.+ and MC.sup.- that correspond to the polarities of the two currents, and the magnetic centers are positioned at optimal magnetic locations.
