In a disc apparatus using a disc as an information recording medium, a vibration caused by an uneven distribution of weight of a rotational member can be prevented. A motor for rotating a turntable of the disc apparatus has a rotor. A plurality of weights are provided in the rotor, the weights being displaced by a vibration generated in the motor due to a rotation of the rotor. The plurality of weights are rotatably provided in an annular space having a center coinciding with a rotational axis of the rotor.
