Abstract
We report a comprehensive study on the protective, functional and microstructural properties of filtered cathodic vacuum arc (FCVA) deposited ultrathin carbon overcoats (COCs), which are being considered as potential candidates for future media recording technology such as heat-assisted magnetic recording (HAMR). Specifically, the influence of the C+ ion energy (50
