Recordable optical element using low absorption materials

摘要

There is disclosed a recordable optical element that has a substrate and on the surface of the substrate, a recording layer and a light reflecting layer. The recording layer has a material with the formula TeaGebCcHdOe wherein a, b, c, d, and e are atomic percents and (c + d) > 40, d > 10, a > 5, b > 5, and e >/=0 such that a + b + c + d + e = 100; and the reflecting layer and the recording layer being selected such that the element Rmax or Rmin (element reflectivity) is about or greater than 70% at about 780 nm.
