Abstract
This study is intended to establish a standard technique for measuring high-density optical disk life expectancy. The life expectancy of archival performance for high-speed recordable optical disks [digital versatile disc-recordable (DVD-R) disk] was examined using two acceleration test models, namely, the Arrhenius and Eyring models, and an analysis of statistical techniques based on the ISO method. Results demonstrate that the statistical distribution of failure time using both acceleration test models follows a lognormal distribution. Thus, we can estimate a standard life expectancy of 95% survival probability with a 95% confidence level for each acceleration test model.
