Paper Abstract

A new azo nickel chelate thin film has been developed for short wavelength write-once optical recording by a spin-coating process. Thermal property of the dye was studied by thermo-gravimetric analyzer (TGA). The azo nickel chelate begins to decompose at temperature 295.6°C, which is 44°C above that of azo, and rapidly decomposes in the narrow temperature range. A dynamic optical recording test on the disc made of this dye indicated that the CNR of written signals was more than 43dB at low writing power and short writing pulse-width using Ar+ laser (514 nm) irradiation in a wide scan velocity range.
