M-Disk is rated to last like ~~100~~ 1000 years. They are also working on a 125 Terabyte CD. Optical storage is the way to go.
so they've solved bitrot? nice
Well yeah but BluRay is still much more expensive and smaller capacity. Lets hope this new 125TB disk works out
The main cause of bitrot in older disks is the organic dyes fading (aside from REALLY cheap disks where delamination was a problem), whereas M-Disc uses an inorganic carbon material
TIL, thanks!
Was it sapphire or something? But one and done. I wonder if you could just keep writing and just "cross-out" the old stuff with that kind of capacity.
Not sure what sapphire means, but here is the article. Just appending records and differential backups would seem to be the way to go.
Sapphire was one of the materials being researched for optical data storage, once upon a time.
"Chinese researchers ............"
OK.
M-Disc is rated to last 1000 years.
