| 摘要 |
A description is given of a rewritable optical information medium having a stack (2) comprising a phase-change recording layer (5) sandwiched between two carbide layers (4, 6), and a light-absorptive layer (7) of a material like Si, Ge, Mo, or W. The light-absorptive layer provides the stack (2) with a slow cooling behaviour. The result is that such a medium can be used for high data rate recording. A user data bit rate (UDBR) of 50 Mbit/s is reported. |
