New Findings from Data Storage Institute Describe Advances in Magnetics

May 6, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Magnetics have been presented. According to news originating from Singapore, Singapore, by VerticalNews correspondents, research stated, "The L1(0) ordered FePt-based medium with a novel thermal design for heat-assisted magnetic recording (HAMR) application has been demonstrated."

Our news journalists obtained a quote from the research from Data Storage Institute, "The proposed seed-then-heat sink approach using the (001) textured Cu3N as the underlayer to induce the MgO (200) texture at room temperature. The high temperature process for FePtX granular film deposition resulted in the decomposition of the Cu3N to Cu and made it a suitable heat sink layer."

According to the news editors, the research concluded: "Our approach eliminated the effect of the boundary thermal resistance and enabled a large thermal gradient during the writing process, which is critical to the FePt-based medium for HAMR application."
