a motor; a main shaft rotated by the motor;
At least one magnetic disk attached to the main shaft, at least one magnetic head, a positioning device for positioning the magnetic head on a predetermined track of the magnetic disk, and a stepping motor for driving the positioning device. In the magnetic disk device, the stepping motor includes a rotating shaft and two flanges that hold the rotating shaft, and the output side flange of the two flanges has a coefficient of thermal expansion equivalent to that of the bearing. A magnetic disk device characterized in that the other flange is formed using a material having a coefficient of thermal expansion different from that of the bearing.
