There have been a number of articles in this newsletter and elsewhere in genealogy publications about long-term storage of magnetic and optical media. Many of us are concerned about the life expectancy of CD-ROM and the newer DVD-ROM disks. Tina Sieber writes in the MakeUseOF web site, “While estimations predict a life time of up to 200 years for optical discs, we can never be sure when they are really going to break. However, by being aware of what determines the life span of optical discs and what causes them to break, you can make choices and significantly increase the survival time of your stored data.”
Tina describes music on CD and movies on DVD disks, but her comments apply equally to computer data stored on DVD-ROM disks.
