Optical recording properties of styryl derivatives for digital versatile disc-recordable (DVD-R)

Abstract

New styryl dyes for the recording layer of digital versatile disc-recordable (DVD-R) were synthesized and analyzed by UV-vis spectroscopy and thermal analyzer. Using these dyes, we prepared two-type DVD-R discs, with/without metallic thin film between substrate and organic buffer layer. The metal-polymer deformation 4.7 GB DVD-R discs were recorded by high-power 658nm-wavelength laser diode and their recording characteristics were evaluated at 650nm wavelength. The optimum writing power and jitter value was in the range of 10 mW and 12 similar to 13%, respectively.
