M-Disc, the DVD that lasts at least a thousand years




by the middle » 11/08/11, 08:14

Hello,
If it's true, it's interesting.
http://www.futura-sciences.com/fr/news/ ... ans_32698/

The lifespan of DVDs is measured in decades, which is not enough for long-term data archiving as in the medical sector or for certain companies. The solution may be the M-Disc from Millenniata. Almost engraved in stone, it would be able to cross the centuries ...

I saw the opposite recently in a store: the DVD which lasts 24 hours after opening by auto chemical destruction of the readable layer.

It is in a waterproof case (probably the O2 which oxidizes the DVD).

It is sold for € 1.

Consumption level we hadn't done better since the disposable camera ... I think ...

For the M-Disc I think it's true (difficult to assess over such a long period it's true but they had to do their calculations ...) but the question will rather be to find readers by 1000 years ... I think ...

last a thousand years we don't ask for so much, but to be more durable than current CDs is not bad

in addition this new dvd seems simpler to manufacture than ordinary dvd: it could be cheaper: it is the high power burner which will be more expensive

MDisc technology:

Image

An ordinary DVD, on the left, with its layer of organic dye, which can crack over time and be affected by high temperatures and humidity, and an M-Disc also cuts in right. The new data storage layer is made entirely of inorganic materials, including metals and metalloids. This layer remains solid even at 500 ° C, and it remains stable in the presence of oxygen, nitrogen, water and other harmful chemicals that can be found in ordinary storage environments. When the layer is irradiated by a focused laser, the intense heat generated melts it and a hole is formed. © Millenniata

FYI, the French company Digipress marketed a tempered glass CD 20 years ago where it is the glass that is etched and not a layer placed on polycarbonate as in the case of M-Disc. What is the lifespan of the glass? AMHA, well over a thousand years ...

Uh and it's easier to melt glass than minerals, right?
The engraving power, in both cases must be very high compared to our conventional engravers (whose power I do not know) ...

Please note, a commercial CD or DVD is not burned, it is produced by injection / pressing of polycarbonate followed by metallization and then varnishing.

And I would add that it would be wise to create readers that do not "snap" after a few years ...
