My father told me he wanted to make USB flash drives of all the scanned and digitized family photos and other assorted letters and mementos. He planned to distribute them to all family members hoping that at least one set would survive. When I explained that they ought to be recipes to new media every N number of years or risk deteriorating or becoming unreadable (like a floppy disk when you have no floppy drive), he was genuinely shocked. He lost interest in the project that he’d thought was so bullet proof.
M-Disk is rated to last like
1001000 years. They are also working on a 125 Terabyte CD. Optical storage is the way to go.so they’ve solved bitrot? nice
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!
Well yeah but BluRay is still much more expensive and smaller capacity. Lets hope this new 125TB disk works out
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.
