摘要： A method for improving magnetic grain segregation in perpendicular recording media includes providing a substrate comprising a rigid support structure, depositing a soft underlayer on top of the substrate depositing an intermediate layer on top of the soft underlayer, providing a plurality of prospective segregants, determining the surface energies and the heat of formation of the prospective segregants and selecting the prospective segregant with a low surface energy and a high heat of formation. The method also includes providing at least one layer with surface energies progressively increasing to minimize the difference between the surface energy of a carbon overcoat and the segregant.
