It called an accelerated stability program. We used them at my old job all the time to check the stability of hair care products.
Basically the products are put in a series of controlled environment constant temperature/humidity rooms. Not sure what they do for discs but for our products the temperatures ranged from 5C to 49C with an ambient control. Other samples were put in high and normal humidity rooms to simulate humidity conditions.
Over a period of years products are pulled out of the rooms and checked against standards for various attributes vs control products. After all the data is collected it is evaluated for differences via mathmatical calculations and the shelf life is predicted. This method is "industry standard" and is amazingly accurate.
Aren't you glad you asked??
