Reliability of Optic Disks

The estimated service life of optic disks at the normal temperature is 20 years by use of the acceleration experiment and Arrhenius figure.The specific properties of mechanics and record of optic disks is tested through environment experiment.The test results indicate that some of the experiments lightly influenced the specific properties of mechanics,the others triflingly affect that of record,such as the reflection rate of recording layer,BER,etc.The way of improving the reliability of megneto-optic disk is raised preliminarily by analyzing the specific properties,the stale mechanism of the base of megnesto optic recording layers and the protective layer.
