Paper Abstract

The method of estimating the reliability of recordable phase change media is examined. The PD disks of 650 MB in total capacity in 12 cm diameter are used as experiment samples. The media are put under the acceleration environment of 80 degree in the temperature 85% in humidity, and change of BER is observed. Two kinds of life (archival and shelf) are tested. As for the disk to be examined, it is necessary to do the acceleration reliability test in a linear area in the destruction limit. Therefore, there is a limit in a possible acceleration coefficient. In the optical disk with long life at present time, it will take extremely long time to presume the final life. In this thesis, the method of estimating the life of a long-lived disk at shorter time is discussed.
