Why is it called CD burning as against copying or pasting or saving?

That’s a simple one, it’s because you are literally burning a CD. CD and DVD burners/writers work by using a laser to burn the surface of the CD or DVD. Making certain portions of the surface darker creates a digital pattern. DVD and CD players read discs by running a laser over the surface and this pattern gives the player digital information that it can interpret as data, sound or video.
