Abstract

There have been many studies of high-speed and high-density recording using phase change media[1-3]. For data transfer rate of higher than 100 Mbps, Sb-Te based growth dominant recording films have quite often been used. Although the high crystal growth rate allows high speed recording, it causes several issues such as high recording power and the decrease of the modulation due to the re-crystallization during writing. Because the increase of the recording power due to the re-crystallization causes severe cross-erase, the recording film with high crystal nucleation frequency and low growth rate is suitable for the high-density (especially for high-track density) recording at the high data transfer rate.
