Abstract :
The refraction index n and extinguished coefficient k of materials can be calculated from their reflection and transmittance measurements with varied wavelengths. The organic and inorganic materials used for optical recording medium materials are examined. The organic dyes show that significant optical constants vary with the laser wavelength, in comparison to the inorganic phase-change materials.
