To achieve magnetic recording densities greater than 10 Tb/in2, the head-disk interface (HDI) spacing is required to be less than 2–3 nm. Thus far, various technologies, such as heat assisted magnetic recording (HAMR), have been studied and developed to achieve such high magnetic recording densities [1]. To ensure the practical applicability of HAMR, it is important to understand the reliability of perfluoropolyether (PFPE) boundary lubricant films and carbon overcoat or diamond-like carbon (DLC) thin films used on the head slider and disk surfaces under heating conditions [2].
