    • The optical storage medium comprises a substrate layer, a data layer having a pit/land data structure with data arranged in tracks on the substrate layer and a nonlinear layer with a super-resolution material, wherein the data structure comprises diffractive pits and lands having a size above an optical resolution limit of a pickup for reading of the data and super-resolution pits and lands having a size below the optical resolution limit, said pits and lands having a defined length with regard to a channel bit length. A diffractive land preceding a super-resolution pit is changed by a first length depending on the laser power of the pickup, and/or a diffractive pit preceding a super-resolution land is changed by the first length depending on the laser power of the pickup, to compensate a phase shift of the super-resolution pit, respectively super-resolution land.
    • 光学存储介质包括基底层,具有凹坑/平台数据结构的数据层,其中数据被布置在衬底层上的轨道中,以及具有超分辨率材料的非线性层,其中数据结构包括衍射凹坑和具有 尺寸高于用于读取具有低于光学分辨率限制的尺寸的数据和超分辨率凹坑和平台的拾取器的光学分辨率极限,所述凹坑和平台具有关于通道位长度的限定长度。 根据拾取器的激光功率,超分辨率凹坑之前的衍射面改变第一长度,和/或超分辨率光阑之前的衍射凹坑根据拾取器的激光功率而改变第一长度 ,以补偿超分辨率坑相移超分辨率的土地。
