Enhanced characteristics of pulsed DC sputtered ultrathin (<2nm) amorphous carbon overcoats on hard disk magnetic media
Diamond and Related Materials, pp. 14-23, 2015.
We report on the unusual tribological, surface and corrosion properties of ultrathin (~1.5nm) amorphous carbon (a-C) overcoats, which have been grown on CoCrPt:oxide-based media using a facile pulsed direct current (DC) sputtering process. The a-C films produced by pulsed DC sputtering are found to show low surface roughness (~1.5Å), low ...More
