    摘要： An optical recording medium wherein the percentage change (|[a2−a1]/a1|×100) of the recording layer thickness (a2) at the recorded site of recording layer (A) after recorded with laser light compared with the recording layer thickness (a1) at unrecorded site of said recording layer (A) is less than 25% and the amount of change (|a2−a1|) of the recording layer thickness (a2) at recorded site of said recording layer (A) after recorded with laser light compared with the recording layer thickness (a1) at unrecorded site of said recording layer (A) is controlled to be less than 15 nm. The optical recording medium can enable recording and playback with high quality using laser of 300 nm to 900 nm. Also provided is a compound comprising a six-membered ring structure composed of four carbon atoms and two nitrogen atoms and a bonded substituted or unsubstituted amino group.

    摘要翻译： 一种光记录介质，其中记录层厚度的变化百分比（| |） <100> 与在记录层的未记录位置处的记录层厚度（a 1）相比，用激光记录的记录层（A）的记录位置处的“SUP”2 < A）小于25％，记录层厚度的变化量（a 2 1） ）与记录层（A）的未记录位置的记录层厚度（a> SUP> 1）相比，用激光记录的所述记录层（A）的记录位置被控制为小于15 nm。 光记录介质可以使用300nm至900nm的激光器以高质量进行记录和回放。 还提供了包含由四个碳原子和两个氮原子组成的六元环结构和键合的取代或未取代的氨基的化合物。
