That is surface rust and normal. You can get new rotors, which will build surface rust quickly due to the inability to coat brake parts. Alternately you can sand and paint the portion bothering you.

There are 2 reasons to replace rotors
1) Warping
2) You let the pads go so long that the metal backing wears deep scratches into the rotor.
Not really new to cars...just never had a car where I cared about what the rotors looked like before...lol. These are the original rotors on the car, and they have about 90,000 miles on them. The pads are about due to be replaced, and while I was doing the pads, I figured I'd replace the rotors since they're probably worn out of spec. Just wasn't sure if there was another option out there since I'm buying new rotors anyway. I didn't really want to paint them as I suck with paint...lol
