Paper Abstract

Correlation of overwriting performance and disk structure of phase change erasable optical disk was investigated using Ge-Te-Sb recording material. It was found that quadrilayered structure is superior in cyclability to trilayered structure because molten material is liable to flow along the track in the case of the trilayered structure. A million cycle BER (bit error rate) stability was achieved by applying new writing method to the quadrilayered structure.
