First positional information of a stage is measured using an interferometer system, for example, an X interferometer and a Y interferometer. At the same time, second positional information of the stage is measured using an encoder system, for example, one X head and one Y head. A coordinate offset is set by performing a moving average of the difference between the first positional information and the second positional information for over a predetermined measurement time, and the reliability of output signals of the encoder system is verified using the coordinate offset. In the case the output signals are determined to be normal, the stage is servocontrolled using the sum of the first positional information and the coordinate offset. Such servocontrol by a hybrid method makes it possible to perform drive control of the stage having stability of the interferometer and accuracy of the encoder together.
