Abstract

We introduced a melt-erasing method of single beam overwrite of a phase-change optical disk. A examination on this method was done using a newly developed In-Sb-Te phase-change optical disk. The carrier to noise ratio (CNR) more than 50dB and the erasing ratio more than 40 dB were obtained. The high CNR and the good erasability were due to the In-Sb-Te phase-change optical disk and the melt-erasing method.
