I haven’t thought about burning CDs in a long time, man that takes me back. Remember Nero Burning ROM?
I think the etymology of the term is that when you’re writing data onto a disk you’re shooting a laser onto it to alter the chemistry and change its color, for which “burning” the data into it makes sense.
It wasn’t the colour, you would burn little bubbles into the disk. The bubbles would deflect a laser and flat parts would not. This would give the 0 or 1 bits.
There were CD- and CD+ versions. I don’t know which is which but one would create a divot, and the other would create a bubble. Either way the laser is diverted away from the sensor.

Ah, that’s what it was! I always thought it was just a different color for 0 and 1, today I learned! That makes more sense when I think about it.
