Longitudinal Magnetic Recording Media with Thermal Stabilization Layers

概要

論文の詳細を見る
We introduce promising longitudinal recording media with enhanced thermal stability compared to conventional media. The media consist of one or more magnetic layers disposed between the recording layer and the underlayer with the magnetization direction of the layers being antiparallel to the adjacent layer or layers. Antiferromagnetic coupling is induced through a thin Ru layer between the Co-based magnetic layers. Comparison with conventional media with the same remanence magnetization and thickness product reveal improved thermal stability and read-write properties for the proposed media.
