ABSTRACT:
An optical data recording media which is optimized to yield maximum absorption of the incident recording light and to be responsive to the light incident over a relatively wide range of angles. A transparent dielectric coating is utilized in combination with a metal layer and provides maximum absorption by the metal layer of the recording light incident at various angles for both S and P polarizations. The selected coatings also yield a high contrast ratio for reflectivity at different wavelengths.
