Improved recording performance and optimized durability of thin film disks with zone carbon overcoats

The idea of zone carbon (ZC) is to use a thicker carbon overcoat in the landing zone and a thinner carbon in the data zone. In this study, we demonstrated the use of a zone carbon scheme to improve recording performance while maintaining the durability of the thin film disk.
