Magnetoresistive read head having an exchange layer

Magnetoresistive read head having an exchange layer

A magnetoresistive (MR) read transducer (30) having an exchange layer (32) adjacent a soft active layer (SAL) (34). The exchange layer (32) generates a transverse bias field which saturates the SAL with little or no sense current.
