Are standard BD-R's chemical or physical?
Discussion
Many of them are HTL (inorganic) which is the entire point of M-Discs, using an inorganic instead of organic dye.
There are LTH BD-Rs (organic dyes) which are shit, but any HTL one should work for medium term archival, and you can identify them in a disc reader software.
Verbatim has a MABL BD-R thing too, which burns off metal instead of changing a dye.
Does Verbatim sell the MABL BD-R's under a particular label? I am running extremely low on M-Discs, and the standard has clearly been diluted by now.
Yes it says MABL on the package.
Like in the branding or fine print? Got an Amazon link?
On the package in the fromt

Oh there we go. It was staring me in the face. Thanks.
My caveman brain wants to believe a physical pit in metal would be preferable for archival purposes. Is Caveman Rich wrong?
Yes, and they likely use better production lines than their unlabeled stuff.
I believe all “non-organic” HTL Blu-Rays use a variation of metal-based layers with permanent changes.
As long as the incredibly thin metal coating is strong. Lots of pressed retail CDs & DVDs succumbed to bit rot due to faulty data layers.
BD-R’s have scratch resistant coatings and usually better protection against delaminating.
I've never used BD much. I didn't think I've had a device with a disc slot since my Wii 😂 the only reason I know is from helping an audiophile friend rip his CD collection to flac when he had some old discs start to discolour & flake. Got him very stressed out.
CD data layer is at the top of the disk directly exposed to the environment
