After the caliper mount is removed, the rotor is free to slide off the hub. Before you remove the rotor, place matchmarks on the rotor and hub so that the rotor will be replaced with the same orientation as it was removed.

There are two holes in the rotor inside the lugs where you can screw bolts. If some persuasion with a plastic mallet on the rear of the rotor doesn't dislodge it, thread two bolts into the rotor through these holes and tighten them evenly once resistance is felt. They will pull the rotor off the hub.
