More and more folks are turning to cloud services like Dropbox to store their oh-so-precious private data, but when it comes to truly valuable info, it's still a good idea to keep a physical backup disc around in case those virtual services crap out on you. Then again, CDs and DVDs scratch waaaaay too easily and have limited shelf lives. If you've ever been screwed by a big gouge across an important backup disc, you might want to check out the new optical media that's hitting the market soon. Supposedly, it lasts forever, and the Department of Defense vouches for its resiliency.
They're called M-Discs and they're being brought to market a start-up company called Millenniata, Link Removed. M-Discs ditch the traditional reflective layer found in standard physical media discs and instead etch the information directly into the body of the multi-layered disc itself, which is made of an undisclosed stone-like substance. Millenniata says that any device that can read a DVD can read an M-Disc – the only special equipment necessary in the whole process is an M-Disc burner.
