Abstract
Recording heads for data storage systems are provided. Recording heads illustratively include a write pole, a bumper, a dielectric layer, and a surface. In some embodiments, a portion of the surface includes portions of the write pole, bumper, and dielectric layer. The write pole, bumper, and dielectric layer are illustratively made from materials that have polishing rates. In some embodiments, the polishing rate for the write pole material is more similar to the polishing rate for the bumper material than it is to the polishing rate for the dielectric layer material.
