A new tech startup Millenniata is developed an optical disc : M Disc which they stay last forever (a 1000 year ) and what more its scratch proof, heat proof and even remains intact if you dip it in boiling water or liquid nitrogen.
Technology behind: M-DISC compared to other DVDs and optical discs.
The technology behind Millenniata (M Disc) is a chemically stable and heat-resistant material which is different from normal DVD or optical discs. The specialty of this technology is that drives made from this cannot be overwritten, erased, or corrupted by natural processes. The normal laser energy employed to write DVDs or CDs cannot successfully write to the patented inorganic and synthetic materials used in the M-DISC
M-DISC stores data in discs by physically altering the recording layer and creating permanent voids or holes where as normal DVDs and other optical discs use organic dyes which get erased or break apart over time which makes optical discs corrupt and unreadable. Also to the technology used in normal optical discs are highly susceptible to temperature, humidity and even sunlight, starting to fade and decay the moment you record data.
Millenniata recording process utilizes higher temperatures and as much as 5 times more energy than any ordinary optical disc. This allows for permanent engraving on the M-DISC, 
what we refer to as pits. These pits are not affected by temperature, humidity and sunlight the same way dyes are, because the pits are permanent. This means when you burn data onto the M-DISC, 
it will last as long as you need it to.
Who need this disk?
Well for anyone who values his data and want to keep the data forever, whether you are business man, photographer, student or literally anyone who have data to keep to forever.
Behind the technology:
Millenniata, in collaboration with LG Electronics has produced this technology which claims to last for 1000 years and they do give you a warranty.
