摘要：
The embodiments of the present invention relate to a method for forming a magnetic read head with pinned layers extending to the ABS of the read head and magnetically coupled with an antiferromagnetic layer that is recessed in relation to the ABS of the read head. Portions of the antiferromagnetic layer and a magnetic layer that are extending to the ABS are removed, exposing a shield. A shielding material is formed on the exposed shield and a seed layer is formed on the shield and on or over a portion of the remaining antiferromagnetic layer. A pinned layer structure is formed on the seed layer and the magnetic layer.
