ABSTRACT:
An object of the invention is to inhibit a turning force of a magnetic disc apparatus from being reduced. In order to achieve the object, there is provided a magnetic disc apparatus having a rotor to which a magnetic disc fixed, and a stator which is filled with a resin between stator coils, wherein a member having a lower expansion coefficient than a thermal expansion coefficient of the resin is arranged between the stator coils.
