Surface energy is an important surface property of a magnetic recording disk There are three predominant factors that influence the surface energy of a disk: (1) lubricant, (2) carbon overcoat and (3) interaction between the lubricant and carbon overcoat. In this work we show how the lubricant thickness and carbon overcoat composition influence the surface energy of the disk Furthermore, we are able to ascertain interactions at the lubricant-overcoat interface by studying the surface energy of the disk
