Nearly Indestructible M-Disc by Milliennata

Millennata brought out M-Discs with a maximum of 4.7 GB of memory. The trick of optical media is that they are extremely durable: M discs can even handle the alternate immersion in boiling water and liquid nitrogen. For this reason, they are particularly well suited for long-term storage because they do not mind changing temperatures. Now Milleniata presents a new Blu-ray version with more memory. 

The new M-Discs Blu-Rays should be available in the second quarter of 2013. You have up to 25 gigabytes and it can be read by any conventional Blu-Ray player. This is a tremendous step forward, because the M-Discs from the year 2011 were only playable on dedicated hardware. Moreover Millenniata has now a distribution partner "Imation", which will distribute the M-Discs under the brand TDK, Memorex and Imation. The production is taken by Ritek.  

M-Discs get their data security, as they can only be described using a special laser and use inorganic material that resembles a stone. Here the data is actually "engraved".
