Recordable optical device including a barrier layer |
摘要 |
For an optical recordable disk, a heat conductive gold layer can be deposited on a phase-change recordable layer to increase the writing threshold. This higher threshold improves the data stability during readout. However, it has been found that there is substantial inter-diffusion between the phase-change layer and the gold layer. The performance is degraded as a result. A barrier layer between the phase-change layer and the gold layer can effectively prevent diffusion and mixing. Using his barrier, the performance is preserved and the data stability is improved.
