    摘要： A method of forming a pole tip topography associated with an air bearing surface (ABS) of a hard disk drive slider is disclosed. The method etches an exposed pole tip region of an ABS at a first angle with respect to the ABS to remove an irregularity from the exposed pole tip region and to flatten the exposed pole tip region. The exposed pole tip region lacks a photo-resist layer. The method also includes etching the flattened exposed pole tip region of the ABS at a second angle with respect to the ABS to form a recession with reference to the ABS.

    摘要： Embodiments of the present invention pertain to forming a head with reduced pole tip recession. According to one embodiment, a pole tip element is formed from a platinum containing material. During diamond like carbon (DLC) processing, hydrogen and hydrogen containing compounds are removed from a vacuum plasma processing environment that contains the head so that an amount of material that is removed from the pole tip element and other non-platinum containing elements associated with the head are approximately the same.
