摘要：
Novel recording media layer structures for reducing the spacing between the soft magnetic underlayer and the writing head have been studied. In this paper, the kink in Kerr loops at zero fields is explained to arise from the depth-sensitive Kerr effect. Novel intermediate layer structures with two (RuCu) or three elements (RuCr:Oxide) are also proposed to reduce the grain size in the intermediate layer. This would, in turn, lead to a reduced grain size and grain size distribution in the CoCrPt:SiO2 recording layer.
