The embodiments of the present invention relate to a magnetic read head with pinned layers extending to the ABS of the read head and in contact with an antiferromagnetic layer that is recessed in relation to the ABS of the read head. The recessed antiferromagnetic layer may be disposed above or below the pinned layer structure and provides a pinning field to prevent amplitude flipping in head operation. In these embodiments of the present invention, the read gap of the sensor, that is the distance between the highly permeable, magnetically soft upper and lower shield layers at the ABS, is reduced by the thickness of the antiferromagnetic layer.
