| 摘要 |
An ablative recording medium comprises a substrate coated with a light reflecting coating which in turn is coated with a light absorptive layer selected from the group consisting of lead phthalocyanine, chloroaluminum phthalocyanine, vanadyl phthalocyanine, stannic phthalocyanine and chloroaluminum chlorophthalocyanine. During recording, portions of the dye layer are ablated or vaporized by an intensity modulated focussed light beam, thereby exposing portions of the reflective layer and recording video information as a reflective-antireflective pattern.
