> Compact Disc is a tradename, and therefore is capitalised. But the logo says "Compact disc", and the term is now used as a generic term for compact disks or compact discs, depending on where in the world they are. Everyone calls them CDs (or maybe CD's).

My headcanon:

- The logo says "dɪsᴄ", like what can be represented on the seven-segment display that would be found on the front of any player even in the '80s.

- They cease being "Compact Discs" and start being "CDs" in ~1994 (region dependent) when they started being pressed with IFPI codes: https://forums.stevehoffman.tv/threads/can-you-tell-if-an-au...
