There are provided an optical recording medium which enables recording and playback with high quality using laser of 300 nm to 900 nm and a novel compound.
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.
A compound comprising a six-membered ring structure composed of four carbon atoms and two nitrogen atoms and a substituted or unsubstituted amino group bonded.
本发明提供了一种光学记录介质,利用波长为 300 纳米至 900 纳米的激光和一种新型化合物可实现高质量的记录和重放。
一种光学记录介质,其中用激光记录后,记录层(A)的记录部位的记录层厚度(a2)与未记录部位的记录层厚度(a1)相比的变化百分比(|[a2-a1]/a1| ×100)小于 25%,且所述记录层(A)的记录部位的记录层厚度(a2)与未记录部位的记录层厚度(a1)相比的变化量(|a2-a1|)小于 25%。a1|)的变化量控制在 15 nm 以下。
一种由四个碳原子和两个氮原子以及一个取代或未取代的氨基键合而成的六元环结构的化合物。
