Paper Abstract

By employing transmission electron microscopy and thermal ana1yis, we examined overwrite repeatability of optical disks using In-Sb-Te alloys, which have high C/N ratio and excellent overwrite modulation characteristics. The overwrite repeatability of more than 105 was achieved by using an In3SbTe2 single-phase ternary compound and heat-flow balanced disk structure.
