ABSTRACT:
A read transducer assembly includes a giant magnetoresistive structure in magnetic contact with a multilayered biasing structure that includes layers of antiferromagnetic material interleaved with layers of soft magnetic material. The magnetic exchange coupling between the antiferromagnetic layers and the soft magnetic layers results in a bias field to the giant magnetoresistive structure that reduces or eliminates side reading by the read transducer assembly. The multilayered biasing structure is located adjacent to and in magnetic contact with either the end or the top surfaces of the giant magnetoresistive structure.
