Abstract

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.
