| 摘要 |
The present invention relates to a master substrate (10) for optical recording comprising a recording layer (12) and a substrate layer (14), the recording layer comprises a growth dominated phase-change material, the chemical properties with respect to chemical agents of which may be altered due to a phase change induced by projecting light on the recording layer. For tracking purposes, the substrate layer comprises pre-grooves (16). The present invention further relates to a method of manufacturing a stamper for replicating a high-density relief structure.
