Abstract

Polymer materials show their impact on optical storage technology for developing high information density and fast access-type memories. A new push-pull azo dye-doped polymer material has been developed by a spin coating process and used for write-once optical media in this paper. The absorption spectrum of the spin-coated thin film show a strong and broad absorption region at the 400 - 550 nm, which matched with the wavelengths of Ar-laser. The optical recording performance of the azo dye-doped polymer thin film show that higher reflectivity contrast can be obtained at lower writing power and writing pulse width using an Ar- laser (514.5 nm) irradiation.
