Estimates on the lifespan of CD- and DVD-Rs vary wildly, from between two and 100 years. In 2004, the U.S. Library of Congress sponsored a study that estimated the shelf life of recordable discs available at that time. It simulated the aging of CD- and DVD-Rs stored in perfect environmental conditions (that is, a room temperature of 50 percent humidity with no sunlight, and no rough handling).

The study concluded that most recordable discs stored in ideal conditions would last at least 30 years, but the results varied wildly by brand. However, it also stated that “discs exposed to more severe conditions of temperature and humidity would be expected to experience a shorter life.”

"Ultimately David Brooks’ tweet and column are just the plaintive whine of someone comfortable with things as they were: Why couldn’t they have stayed that way? The answer is not all that surprising: Because they weren’t ever that way for long, you just came up in a moment. And now that moment’s over. Get on with it, or it will get over you."
