Digital media is a double-edged sword. Digital data itself can be duplicated an unlimited number of times without any generational loss – meaning it can theoretically last forever. But digital storage on physical media is subject to failure – and that failure can render the data inaccessible. In other words, archivists (including you) have to transfer data before the media fails.
And we’re already entering an age when one of the most popular formats is reaching the start point for common failures.
A report by Tedium (republished by Motherboard) demonstrates one of the most alarming failures. Some media, evidently using faulty dyes, can fail in under ten years, via something unpleasantly dubbed “disc rot.”
