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
