摘要: An optical disk records digital information in optically-reflective layers that each vary thickness between constructive interference of a monochromatic light and destructive the said light. The difference intensity reflected beam subjected to interferometric is used communicate data from detector. provides for multiple are tuned response at correspondingly different wavelengths Another embodiment present invention mass-production process making such an disk. variation includes emitting or absorbing depending on dopants.
