Abstract
A magnetoresistive read sensor is described. The sensor is a magnetically responsive stack positioned between top and bottom electrodes on an air bearing surface. Current in the sensor is confined to regions close to the air bearing surface by a first multilayer insulator structure between the stack and at least one electrode to enhance reader sensitivity.
