In this paper, the cyanine thin films and CD-R samples were prepared by the spin-coating process. The transmission, reflection and absorption spectra of the cyanine thin films were measured by the spectrophotometer and the reflection and the absorption of this cyanine thin film are high enough for optical recording at 780 nm. The reflection of multi-layers reached up to 75%. The results of the optimum recording power measurement indicate the optimum writing power is about 7 mW.
