<p>The head (10) comprises a soft adjacent layer (SAL) (12), a non-magnetic decoupling layer (14), a magnetoresistive (MR) layer (16), an antiferromagnetic (AFM) layer (18), conductive leads (20, 20') and magnetic shields (26, 26'). Longitudinal bias, for domain suppression, is applied to the end regions (2) of the sensor. The MR layer is in electrical contact with the AFM layer which is patterned to cover the end regions of the sensor. Only the end regions are exchange biased so that the MR layer is longitudinally biased in a single domain mode in the end regions.</p> |
