Optical record blank and information record |
摘要 |
A multi-layer optical record blank and information record comprises a light-reflective layer, a light-transmissive layer, a light-absorptive layer, and a heat-sensitive information layer wherein the thicknesses of the layers are chosen to achieve a low-reflection condition. Information is recorded as variations of an optical property in the information layer indirectly heated by light absorbed in the absorptive layer.
