What is the M-DISC?
The M-DISC is the first ever permanent file backup disc that lasts forever. Unlike computer hard-drives and optical discs (CD and DVD) that suffer from decay, destroying the files you were trying to preserve and protect, the M-DISC cannot be overwritten, erased, or corrupted by natural processes. Best of all, you can access your data anywhere and anytime. It is the new standard in digital storage.

I hope that people who recorded information this way will be able to find a device to read this disk in 5 - 10 years...
