一种新的光致变色络合物M1－β（TCNQ），可作为可擦式光盘的良好存贮媒质。本文对这种薄膜进行了静态和动态测试，并对不同金属比的材料作了比较。已得到的结果为：信噪比约50dB，写入度30dB，擦除度28dB，反复擦除次数＞10。因此近期可望在数字式音像记录方面成为一种实用化材料。
A new photochromic complex, M1-β (TCNQ), can be used as a good storage medium for erasable optical disks. This paper has been static and dynamic testing of such films, and compared the different metal ratio materials. The results obtained are: signal to noise ratio of about 50dB, writing degree 30dB, erasing degree 28dB, repeated erasing times> 10. So in the near future it is expected to become a practical material in digital audio-visual recording.
