Abstract :
In this study, we developed a novel bilayer overcoat on a functional tape head which exhibits long-term wear durability with commercial tape in an actual tape drive environment. The overcoat used in this work is a ~ 20 nm bilayer overcoat structure comprising a composite interlayer of amorphous silicon/silicon nitride (Si/SiNx) after bombardment with high energy C+ ions, followed by a ta-C layer deposited atop .
