利用结晶软底层（c-SUL）成功制备了基于 CoCrPt-SiO2 的垂直记录介质，该介质具有薄的中间层和磁性层中晶粒的窄 c 轴色散。记录性能测试结果表明，c-SUL 介质比非晶软底层 (a-SUL) 介质表现出更高的可写性。 c-SUL 的噪声可以降低到低于 a-SUL 的噪声
CoCrPt-SiO2-based perpendicular recording media with a thin intermediate layer and narrow c-axis dispersion of the grains in the magnetic layer were successfully prepared with a crystalline soft underlayer (c-SUL). The recording performance testing results show that media with c-SUL exhibit higher writeability than those on amorphous soft underlayer (a-SUL). The noise from c-SUL can be reduced to be lower than that from a-SUL
