> M-DISC – DVD/Blu-ray compatible discs citation needed. My DVD/Blu-ray writer does not support M-DISC > may last up to 1000 years or may not. Who knows ?

The discs are entirely compliant with the Blu-Ray spec, there is no “compatibility” mark; anything made in the past 10-15 years should work fine. Your writer may be out of spec?

Apparently original M-Disc DVDs required a more powerful laser than normal, but that is not the case for Blu-Ray.

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 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?

Confusingly you need an MDISC writer for some but not all disks.

Any bluray reader will work to read tho.

There's just no mass-market appeal?

Large storage hyperscalers or whatever just use tape?

I can't wait for tape patents to expire.

> Verbatim Japan claims that M-DISCs now use a titanium layer to prevent moisture ingression and to provide environmental stability

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.
