In an optical disk device of the present invention, a spindle motor is separated into (1) a first motor unit composed of a bearing member, a bearing support for supporting the bearing member, and a turn table fixed to a rotor magnet and (2) a second motor unit provided with a first stator coil. During a cartridge loading operation, after the first motor unit is moved towards an optical disk, the second motor unit is slidably moved to a space created by the movement of the first motor unit so as to be rotatably driven as a spindle motor, thus realizing a thinner spindle motor.
