Paper Abstract

The excellent stability of GeTe-Sb2Te3-Sb phase change disc media was demonstrated in accelerated aging studies. The disc was composed of the pseudo ternary alloy active layer of GeTe-Sb2Te3-Sb, ZnS-SiO2 dielectric layers and Al quadrilayer rapid cooling structure. This structure leads high performance C/N ratio of 55dB and more than 30dB eras ability with wide plateau power dependency. We measured the archival and the shelf characteristics of C/N and bit error rate (BER) as a function of exposure time for discs exposed to 80 degrees C 80% RH, and 90 degrees C 80% RH. From the Arrhenius plot, the life time of the phase change type disc media were expected to be longer than 60 years in 32 degrees C 80% RH environment.
