Optical disk |
摘要 |
An optical recording member is prepared by coating a thin layer of a colloidal dispersion, of minute particles of certain transition metals or their oxides in a polymeric binder, onto a substrate. The optical recording member may be made to achieve anti-reflecting conditions at the marking wavelength by making the substrate reflective and by using proper thickness for the dispersion layer.
