Abstract
A magnetoresistive read head has read head layers that are shaped to form an air bearing surface and a sensor stripe cavity with an open side at the air bearing surface. A sensor stripe is deposited in the sensor stripe cavity. The sensor stripe has a front surface that is set back from the air bearing surface to define an encapsulation cavity extending from the front surface to the air bearing surface. An encapsulation layer is deposited in the encapsulation cavity. The encapsulation layer encapsulates the front surface.
