Abstract

The writing sensitivity of dye-binder optical recording media has been defined as the rate of change in the recording response of the medium as a function of laser power. That response was measured by the electronic readout of the recorded pits and shown to be a function of the viscosity of the binder. The variation in dye-binder media sensitivity was 98% accounted for by variations in binder viscosity and writing laser power. For nonpolymeric systems, a more general regression model was formulated using the glass-transition temperature of the recording medium as a substitute for its viscosity. Thus, for any given dye-binder system, writing sensitivity can be largely predicted from the dye T_g, the binder T_g, and their relative concentration, assuming optimum optical efficiency.
