The head(s) being dirty is the number one cause of a bad read. Second would be a dirty disk, followed by just plain bad media. You may find that you have to clean the surface of the disk. Make sure you use 91% alcohol. You don't want to use the lower percentage because it leaves a water residue that binds with the oxide forming a crust. A soft cotton swab and alcohol (with no real pressure) is the best way to clean the disk. Ideally, you should have something that turns the disk while you cleaning it.
