I procrastinated changing the front brake pads (and it even passed a NY safety inspection...what a joke) and when I did, on one of the pads there was no pad left and the outer 3/4" in diameter (on one side) of the rotor was scratched up a bit, but not very bad. Wanting to get it done quickly and cheap and a Sunday, I just wirebrushed a bit and poped new pads in and was good to go.
They are semi-metalic pads. So over time as things wear, will the rotor become smoothed out?
