N2 - Well-segregated grain structure with narrow c-axis distribution is required for CoCrPt based perpendicular recording layers. However, the enhancement of epitaxial growth of the CoCrPt grains by using Ru of CoCr seed layers, for example, is likely to prevent the Cr segregation to the grain boundary, resulting in the increase of intergranular exchange coupling. In this study, SiO2 was added to the CoPtCr recording layer to enhance the grain segregation, and microstructure, magnetic properties, and recording performances for these media were discussed.
