How does ripping a CD/DVD work exactly? Is it similar to copying or does it leave the CD/DVD unusable?
I've never ripped CDs or DVDs before for any reason and am curious how this works since I have some stuff I wanna see about backing up but am nervous about ruining the disc. I've tried looking this up, but every time I do, I obviously am searching for the wrong thing because I have never found the info I'm looking for.

Discs are harder to ruin than they're made out to be. My best example is a physical copy of grand theft auto san Andreas for the original Xbox. I got a free old copy that was considered useless, because it wouldn't read, the shiny side of the disc was scratched pretty deeply. I took it to the game store and told them "I know this probably won't work, but humor me, run this through the resurfacer please", which cost me $2. They have a $30,000 machine which actually grinds an even surface on the shiny side, adding a new layer of plastic they said, but it did in fact work first try. I still use that disc to play the game with no issues whatsoever. If anything, it's the least glitchy copy of GTA I own physically.
If you look at the layers, the shiny side (bottom) of a CD is a thick layer of plastic. The data is actually on the other side of that plastic, protected by a thin sheet of aluminum foil and lacquer on top. Even a deep scratch on the bottom is unlikely to reach the data, so resurfacing should be very effective.
However, a deep scratch on the top can easily puncture the metallic layer and damage the actual data.
DVDs and Blu-ray have extra layers and are a bit more complicated, but it's a similar design
I learned that data was on the top side at a very young age. I put a sticker on top of a CD and a couple years later peeled it off and the image came off too. I tried to play the CD and realized my mistake. I think I was around 7. Luckily it was just kid's Christmas songs and nothing important lol.
