A stage system includes a movable stage, a first driving mechanism, having magnet and a coil unit, for moving the stage along a predetermined direction, the coil unit including a coil and a yoke, wherein the magnet is connected to the stage side, and a second driving mechanism for moving the coil unit along the predetermined direction. While a position or a speed of the stage is controlled as the stage is driven through the first driving mechanism, the coil unit is moved substantially in synchronism with the stage.
