我们已经研究了双层相变记录介质的记录特性，该记录介质用于使用蓝-紫激光（波长405 nm）的系统，其数值孔径为0.65并且光入射在具有凸台和凹槽格式（HD DVD）的0.6 mm厚的基板上。为了实现其束斑尺寸的更高存储密度，已经将许多技术结合到介质中，例如铋取代的伪二元GeSbTe合金记录膜和氧化铪基界面层材料。36 GB的用户容量的可行性已成功得到证明。
We have investigated the recording characteristics of the dual-layer phase-change recording media for a system that uses the blue-violet laser (wavelength of 405 nm), with the numerical aperture of 0.65 and light incidence on 0.6-mm-thick substrate having the land and groove format (HD DVD). In order to achieve higher storage density for its beam spot size, a number of technologies have been incorporated into the media, such as the bismuth-substituted pseudobinary GeSbTe alloy recording film and hafnium oxide-based interface layer material. The feasibility of the user capacity of 36 GB has been successfully demonstrated.
