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.
