sg-ntu-dr.10356-471622023-03-11T17:40:28Z Ruhenium as diffusion barrier for carbon overcoat of magnetic recording media Wang, Jianhui Sam Zhang Shanyong School of Mechanical and Aerospace Engineering DRNTU::Engineering::Mechanical engineering 191 p. Degradation of the magnetic and tribology performances due to diffusion from carbon overcoat is one of the concerns for future magnetic recording media. In this work, a novel film structure with ruthenium (Ru) interlayer in between the magnetic layer and the carbon overcoat has been investigated. Introduction of an ultra-thin Ru diffusion barrier is aimed to prevent carbon diffusion and minimize magnetically dead layer formation. Selection of Ru film deposition process, impact of carbon on magnetic films, carbon diffusion behavior, barrier mechanism of Ru layer, characterization of carbon films deposited with Ru interlayer and their anti-corrosion performance are covered in the project. All carbon films are prepared by hot filament Plasma Enahnced Chemical Vapor Deposition, and other films are deposited by the magnetron sputtering technique.
