Abstract
We report playback performance results of volumetric optical data storage disks that are made from a new class of light-absorbing (photo-chromic) compounds. The disks are first exposed to a simulated space environment. In order to simulate the space environment, a vacuum oven bakes the disks for certain amount of time at a designated temperature. Test results in this temperature study are fit into an Arrhenius model. Disks are also exposed to radiation doses similar to those found in a space environment. Disks fail in high temperature and large proton-dose conditions. Heavy ions do not cause significant disks failure. The prevention of disk failure due to harsh space environments is also discussed.
