摘要：

A new insight into the amorphous nature of the recorded bits in optical phase-change recording. Pressures up to 5-6 GPa are expected upon melting of a confined bit while we cannot concluded that drives the bits into the amorphous state, the results shown in this paper clearly demonstrate that pressure is an important factor for the amorphization process in a device structure and should be considered on the way for improvement of current and development of novel optical discs and electrical phase-change memories for future uses.
