通过薄膜成核形成的贵金属的不连续膜对于光存储应用表现出有吸引力的性质。在三层结构中使用2.0-3.0 nm的金层可以实现比更传统的碲基系统更低的写入能量。薄膜的不连续性极大地影响了这些薄膜的写入特性。这是由于这样一个事实，即写入点现在是通过激光诱导烧结的小金属岛，而不是通过薄膜烧蚀发生的连续膜。
Discontinuous films of noble metals formed by thin‐film nucleation demonstrate attractive properties for optical storage applications. Writing energies lower than those for more conventional tellurium based systems have been achieved using 2.0–3.0‐nm gold layers in a trilayer configuration. The discontinuous nature of the film is shown to greatly influence the writing characteristics of these films. This is due to the fact that written spots are now formed through laser induced sintering of the small metallic islands, rather than by film ablation that occurs for continuous films.
