[Problem]: An optical recording medium having a capability of recording and/or reading high density optical information using a short wavelength laser light is provided.
[Means to Address the Problem]: The optical recording medium has a capability of recording and/or reading high density optical information using a short wavelength laser light having a wavelength of 350 nm to 530 nm. The optical recording medium has a recording layer containing a metal complex compound and formed on a substrate. The metal complex compound is composed of a cyclic β-diketone azo compound represented by the general formula (I) or general formula (II) and a divalent metal ion coordinated to the cyclic β-diketone azo compound.
问题提供一种利用短波长激光记录和/或读取高密度光学信息的光学记录介质。
[解决问题的方法]该光学记录介质能够使用波长为 350 纳米至 530 纳米的短波长激光记录和/或读取高密度光学信息。该光学记录介质有一个记录层,其中含有一种金属复合物,并形成在基底上。金属络合物由通式(I)或通式(II)表示的环β-二酮偶氮化合物和与环β-二酮偶氮化合物配位的二价金属离子组成。
