"I did not know that!" as Johnny would say...
Should you store treasured data on disks?
Preserving precious data, such as pictures and home videos, on CDs and DVDs could do more damage than good in the end.
"We were surprised to see that the lifetime of discs, some of which were designed to last for centuries, actually rarely lasted longer than five to 10 years," said physicist Franck Laloe.
"In the most severe cases, which were happily quite rare, the data on some discs lasted just one year," he said.
Unlike audio and video tapes that wear out with play, discs are read with a laser so there is no physical contact.
However, the surface which contains more than seven miles of data is deteriorating with age.
