摘要

在预开槽聚碳酸酯基底上采用旋涂法制备了聚氰胺薄膜，并对其光存储性能进行了研究。薄膜在830nm波长处的反射率和吸光度足够高，可以进行光存储。在最佳记录条件下，单层磁盘的载噪比为58 dB。载波噪声比和载波信号电平均与激光记录前后薄膜反射率变化的对数成正比。

Optical storage performance of a cyanine-in-polymer film

A cyanine-in-polymer film was prepared by spin-coating process on pregrooved polycarbonate substrate, and its optical storage performance was studied. The reflectance and absorbance of the film at 830 nm wavelength are high enough for optical storage. With optimum recording condition, 58 dB of carrier-to-noise ratio was obtained for single layer disk. Both of carrier-to-noise ratio and carrier signal level are proportional to log of the reflectivity change of the film before and after laser recording.
