A start-up by the name of Cranberry is claiming that it's DiamonDisc product can last for 1000 years without any deterioration. If true, that's great, but will you even have the equipment to read the media at that time?
Cranberry's disks are supposed to be so durable and long-lasting because they "contain no dye layers, adhesive layers or reflective materials that could deteriorate." Supposedly data is etched far more deeply into the disks than with traditional DVDs (using Cranberry's special burners, of course). You can either buy one of those burners for five grand or upload your data to the company's website and let them do the hard work for you. Either way, the longevity of these disks seems a little bit too good to be true. [Computer World via Slashdot]
