    • The optical storage medium comprises a substrate layer, a data layer, and a nonlinear layer with a super-resolution structure disposed on the data layer, wherein pits and lands having a size above a diffraction limit of a pickup for reading of the data establish a first and a second level of the data layer, and pits and lands having a size below the diffraction limit of the pickup are arranged on a further level of the data layer. In a preferred embodiment, pits having a size below the diffraction limit are arranged on a third level and lands having a size below the diffraction limit are arranged on a fourth level of the data layer. The optical storage medium is in particular a read-only optical disc comprising a phase-change material, for example AgInSbTe, for providing the super-resolution effect.
    • 光学存储介质包括衬底层,数据层和设置在数据层上的具有超分辨率结构的非线性层,其中具有大于读取数据的拾取器的衍射极限的凹坑和焊盘建立数据 数据层的第一级和第二级,并且具有低于拾取器的衍射极限的尺寸的凹坑和焊盘被布置在数据层的另一层上。 在优选实施例中,具有低于衍射极限的尺寸的凹坑被布置在第三层上,具有低于衍射极限的尺寸的平台被布置在数据层的第四层上。 光学存储介质特别是包括用于提供超分辨率效果的相变材料(例如AgInSbTe)的只读光盘。

    • The optical storage medium comprises a substrate layer, a data layer arranged on the substrate layer, a first nonlinear layer with a first super-resolution structure arranged above the data layer, and a second nonlinear layer with a second super-resolution structure arranged above the first nonlinear layer, the first nonlinear layer comprising a material having an increased reflectivity when irradiated with a laser beam and the second nonlinear layer comprising a material showing a transparency when irradiated with a laser beam. The first nonlinear layer comprises in particular a semiconductor material of one of the III-V semiconductor family having a low band-gap. And the second nonlinear layer comprises in particular a phase change material, for example SbTe or AIST.
