Abstract

Statistical analysis on a life time probability of optical recording media is studied. Byte error rate change under accelerated environments was applied to plot on an Arrhenius' scale. Assuming an error generation model where an error is caused by combination of noise generated in a disk and drive, following equation can be obtained; BER = Ao exp [ C exp( - Ea / kT ) ) • t 1. The analysis result suggested that the life time probability distributed normally on an Arrhenius' time scale. Experimental results on high temperature and high humidity accelerated test were in good agreement with the analysis. The life time of 99.9% our magneto-optical media were expected to be longer than 25 years in an office environment.
