Abstract

A sputtering process was used to reduce the grain size and the media noise in longitudinal media. The process included the exposure of oxygen onto the surface of Cr-based seedlayers with the thickness of 0.5 nm. It was found that it was essential to utilize a very thin Cr-based seedlayer with a high affinity for oxygen, a high melting point and which forms an island-like structure to effectively reduce the media grain size and to improve the media signal-to-noise ratio.
