An excellent option for long term storage
3 January 2016
I am happy that these are available in India! They're not particularly easy to find. If you are reading this, chances are that you have heard of M-Discs already. I personally found out about them a few years ago, while searching for long-term data storage.
Migrating data from old to new media is a necessary chore, part of life in the digital age. We have multiple options to spread out the risk of data loss: HDDs, tape, discs, flash memory, and the cloud. The way I see it, M-Discs are a welcome addition to this arsenal. One doesn't even have to change one's existing strategy. Simply write to M-Discs, in addition to the rest, and keep them safe.
You'll need a capable writer. So when I bought a new PC, I made sure to get an LG DVD-writer, marked as such. (Of course, it would be ideal if normal writers could do the job, and this is THE one stumbling block to adoption in my opinion.) The discs come in regular jewel cases, which are in turn sheathed in cardboard sleeves (see picture). The materials used are of good quality. The label sides are inkjet printable. I used a marker pen on the inner edge next to the hole, avoiding the data bearing areas (see picture; writing has been blurred). The reasons being, some of my very old discs show signs of the ink seeping into the material, and this is also recommended by at least one archival organisation.
Now, the question is, will these really last 1000 years? As far as I'm concerned, if they turn out to be readable after my death decades later, they would be worth it.
