A method and system for providing a magnetic writer are described. The method and system include providing a bottom antireflective coating (BARC) on a portion of the magnetic writer. The BARC has a low reflectivity. The method and system also include providing a barrier layer on at least a portion of the BAR and providing a mask on at least a portion of the barrier layer.
