Abstract:
A magnetoresistive read sensor with improved sensitivity and stability is described. The sensor is a trilayer stack positioned between two electrodes. The trilayer stack has two free layers separated by a nonmagnetic layer and a biasing magnet positioned at the rear of the stack and separated from the air bearing surface. Current in the sensor is confined to regions close to the air bearing surface by an insulator layer to enhance reader sensitivity.
