Abstract

The lifetime and reliability of optical media are discussed on the magneto-optical (MO) disk media. The experiments were applying the method conventionally used for MO disk. Based on accelerated aging experimental study, which the magneto-optical disk media are subjected to conditions of high temperature and high humidity, the reliability lifetime was obtained by analyzing the change of BER and CNR at high temperature experiment. The rate of failure was measured and the data were extrapolated to obtain rates of failure under the ambient conditions. We predicated the reliability life of MO disks by using the Weibull method. The research provided that the lifetime of magneto-optical disks was sufficiently long.
