You can definitely put DRM-protected content onto the physical CD media - that is exactly what SACD is. But then it isn't an audio CD, even if it will play on a regular CD player. Search for "nonstandard or corrupted" on the Wikipedia page https://en.m.wikipedia.org/wiki/Compact_Disc_Digital_Audio .
It's my understanding that only conforming CDs can carry the CD logo. It's usually on the case, not the disc itself, and it isn't always there, particularly when the case isn't a jewel case. All the same, I think that most things that look like CDs are conformant.
Yeah, but I imagine that CD logo is a "stamp of quality" of sorts that tells you that the disc inside fits an agreed upon, unified set of standards. And one of those standards is "no DRM."
Point was, if that standard was created or updated today, there's no shot that they wouldn't require DRM.
Maybe I'm wrong though and that's not at all what the CD logo means.
That's true, but they did already try it and it didn't catch on. There's a section about it on the Wikipedia page ("Copy protection").
That section also mentions that Philips stated that these discs couldn't have the CD logo on them. Since Philips was behind SACD, together with Sony, you'd think they wouldn't have imposed that restriction on themselves if they had the choice.
I know GameCube discs had a sort of copy protection built in (don't remember exactly how it worked, but it was pretty creative if I recall). I don't think they had the CD logo on them though.
