Abstract

A new azo metal chelate thin film has been developed for digital versatile disk recordable (DVD-R) by means of a spin-coating. The absorption of the film matches very well with the wavelength of the GaAlInP semiconductor diode laser (0.63 approximately 0.65 μm). Thermal property of azo metal chelate indicates that the rapid decomposition of the dye happens in the narrow temperature zone. The optical recording performance of the azo nickel chelate thin film shows that high reflectivity contrast (34%) can be obtained at low writing power and short writing pulse-width using He-Ne laser (632.8 nm) irradiation. The average jitter of 5-in DVD-R disk after recorded with optimistic power on DVD-RT650 tester is less than 12%.
