Paper Abstract
The international DVD standard, ECMA-267, for compact discs with improved storage capacity is based on a semi- transmitting mirror. This coating provides a top memory layer that permits reading an opaque second mirror layer underneath. According to the standard, the top layer should have a reflectance in the interval 18-30 percent and simultaneously sufficient transmittance to permit a reflectance in the same interval from the bottom mirror layer, all at the reading wavelength 650 nm. The standard also includes the optical effects of the 550 micrometers polycarbonate disc and the 55 micrometers spacer layer used for protection.
