Another possibility is that you have play at the hub, or the wheel isn't properly tight in the fork. This allows the action of the brake on the disc to move the entire wheel over.
Step one, before anything else, is to see if the rim can be pushed to the side easily. I'm only talking about free play here, not whehter you can flex the wheel sideways against spoke tension.
Otherwise, do as Hillrider said, and check to see where the wheel is "centered" now. If it's off center remove it and remount it backward (disc on opposite side) and see if the rim switches sides. If so, you're wheel is not dished (centered on the hub) properly, and needs the spokes reworked to move the rim over.
