M-DISC – DVD/Blu-ray compatible discs that may last up to 1000 years

The drives to read them (Blu-rays) will be the problem. Pioneer stopped manufacturing them in 2024, only LG drives are available now.

Coincidentally I just bought one, they’ve doubled in price now recently.

Also bought some M-Discs to try. They’re half the price in Japan (Amazon) compared to Germany.

I have a few of these drives. They also rip discs very accurately. Bit-identical to my Plextor, at a fraction of the price. But sadly no ripping software offers these the verification logging that is required for redump approval.

From what I understand, Verbatim no longer manufactures true M-DISC media. https://www.reddit.com/r/DataHoarder/comments/1i0ky6v/what_h...

It's all just MABL now.

I wonder why every types of discs seem to be entering a de facto deprecated state over the last ~10 years, especially inorganic types are. Is it simply because everyone's on Netflix? Or could it be environmental/material cost issues?

I believe these discs are made by transferring materials by vaporizing them in a series of big vacuum chambers, maybe those materials are toxic and/or China dominated and nobody wants to deal with them anymore?

I bought 3 burners and burn 2x copies of every 100GB disc. Only Verbatim burners seem to not fail with 50+Gb discs. By the way!

Every few years or so I flirt with the idea of backing up to M-Disks. Then I remember how slow and low density they are.

For recording and forgetting, I recently played with LTO, again.

But I always end up at local HDD + remote AWS Glacier.

This is the only storage media I trust to outlive me. Everything else, including paper, will degrade.

Even the largest 100GB disk seems too small nowadays

citation needed. My DVD/Blu-ray writer does not support M-DISC

or may not. Who knows ?
