  • Ablative optical recording medium
    Patent number: 4242689
    Abstract: An ablative recording medium comprises a substrate coated with a light reflecting layer which in turn is coated with a light absorptive layer of di-indeno[1,2,3-cd:1',2',3'-lm]perylene. During recording, portions of the light absorptive layer are ablated by a modulated focussed light beam, thereby exposing portions of the reflecting layer. Video information is recorded as a reflective-antireflective pattern.
