Abstract

Achieving disk overwrite at a high-data-rate depends on increasing both the disk revolving speed and recording bit density. This work was done to estimate the possible data transferring rates that can be expected in the near future. It is projected that combining the typical phase-change material Ge-Sb-Te and a `thermally-balanced structure' to decrease over-write distortion, several 10 Mbps will soon be obtained by a red laser and more than 100 Mbps will be obtained by a blue laser.
