    • An information storage medium with stabilized inclusions comprised in an information layer and a method of stabilizing the inclusions in the information layer is disclosed. The information storage medium comprising a carrier substrate and a stack of layers supported by the carrier substrate, wherein at least one of the layers in the stack of layers is an information layer, the information layer being a layer comprising a GeSbSn- based phase-change composition, the phase-change composition further being capable of supporting at least a first and a second structural phase, and wherein a shape of an inclusion of the second phase in the first phase is stabilized in a cooling process by having an atomic percentage of Sn in the phase-change composition in the range of 10 to 20%. The information storage medium may be an optical storage medium where the stabilization is a phase stabilization so that inclusions of an amorphous phase in a crystalline phase remain in their intended form, i.e. remain in the amorphous phase in the region as intended from the write laser irradiation.
    • 公开了一种包含在信息层中的具有稳定的夹杂物的信息存储介质和稳定信息层中的夹杂物的方法。 所述信息存储介质包括载体衬底和由所述载体衬底支撑的层叠层,其中层叠层中的至少一个层是信息层,所述信息层是包括基于GeSbSn的相变 所述相变组合物还能够至少支持第一和第二结构相,并且其中所述第一相中的所述第二相的夹杂物的形状在冷却过程中通过使Sn的原子百分比稳定 相变组成为10〜20%。 信息存储介质可以是其中稳定化是相位稳定化的光学存储介质,使得结晶相中的非晶相的夹杂物保持为其预期形式,即如从写入激光照射预期的那样在该区域中保留在非晶相中 。
