ABSTRACT:
The medium comprises a bilayer stack constituted of an inorganic layer (30) and a semi-reflecting layer (32). The inorganic layer (30) can be deformed under the effect of light radiation (34) passed through the semi-reflecting layer, which lowers the reflection coefficient of the stack.Application to irreversible recording of information data, for example on discs.
