Recordable optical media with thermal buffer layer

摘要

The invention is directed to a recordable optical data storage medium that includes a thermal buffer layer formed between a substrate and a recording dye layer of the recordable optical data storage medium. In addition, multi-recording-layer optical media are described, which incorporate such thermal buffer layers between a recording dye and a substrate, and also between another recording dye layer and a spacer layer. In accordance with the invention, the thermal buffer layer or layers comprise a silicon-oxi-nitride (SiO_XN_(2/3)(2-X)), wherein X is between approximately 0.1 and 1.9.
