Abstract

In this chapter, a new bi-layer overcoat structure is proposed by introducing an effective adhesion interlayer of SiNx such that low ion energy C+ deposition can be employed for the growth of the carbon layer while maintaining good adhesion and high sp3C bonding. In this way, the enhanced functional properties of the ultrathin carbon-based overcoat can be achieved, whereas the low energy deposition of the carbon layer would not detrimentally affect the magnetic performance of the media.
