The solid immersion lens can be used into an optical storage system It provides the high NA of the system and uses the evanescent wave to produce extremely small optical spots Two proposals about a SIL are given out here The first one is that the protecting layer of the recording layer can be used as one part of the hemi spherical SIL So the recording layer is not polluted The second one is that a SIL can be used at same time in a double layers storage The first recording layer is used a...

固体浸没透镜用于光存储光学系统增大了光学头物镜的数值孔径，利用近场倏逝波读写，减小了光斑的直径，提高了存储密度。文中建议：(1)将半球SIL分割成两部分，其中一部分由存储媒质的保护层充当，避免直接污染记录层；(2 )在半球SIL单层读写的基础上，再将第一层记录媒质作为SIL的一部分形成超半球齐明SIL ，以实现双层存储。并对此时的近场进行了解析分折
