Can CDs go bad?
Well-cared-for CDs can last many decades — even centuries. But storing a disc in a hot car or playing it often can eventually lead to “CD rot.” “By increasing the relative humidity and temperature, you’re increasing the rate of chemical reaction occurring,” she says.
How long do unused CDs last?
3 Answers. According to the US National Archives: According to the Optical Storage Technology Association (OSTA), the unrecorded shelf life of a CD-R/DVD-R disc is conservatively estimated to be between 5 and 10 years.
How long does it take for a disc to rot?
Among the manufacturers that have done testing, there is consensus that, under recommended storage conditions, CD-R, DVD-R, and DVD+R discs should have a life expectancy of 100 to 200 years or more; CD-RW, DVD-RW, DVD+RW, and DVD-RAM discs should have a life expectancy of 25 years or more.
What is the longest a CD can be?
Standard CDs have a diameter of 120 millimetres (4.7 in) and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 MB of data. Capacity is routinely extended to 80 minutes and 700 MB by arranging more data closely on the same sized disc.
Are old CD players better?

How do you store CDs long term?

Why do CDs stop working?
CD degradation can be caused by mishandling or improper storage, but disc rot is typically caused by a chemical reaction with the reflective layer of the disc.

Why do CDs only hold 80 minutes?
This is uncompressed audio data, and it requires a lot more space than MP3 files, AAC files, or any other type of compressed audio file. A minute of CDDA audio always takes up the same amount of space on the disc, which is why you can only burn a maximum number of minutes to a disc.
Why is a CD 74 minutes?
