Abstract
A method for enhancing thermal stability, improving biasing and reducing damage from electrical surges in self-pinned abutted junction heads. The method includes forming a free layer, forming first hard bias layers abutting the free layer and forming second hard bias layers over the first hard bias layers discontiguous from the free layer, the second hard bias layers being anti-parallel to the first hard bias layers, the first and second hard bias layers providing a net longitudinal bias on the free layer.
