ABSTRACT:
A motor 40 for rotation driving a magnetic disk is comprised of a rotor 41 and a stator 42 assembled with the rotor. The rotor has a central cone 41-11 with a closed top at the center of a casing 41-1, the central cone having a trapezoidal configuration in cross section and being projected upward. A disk table 43 is fixed to the closed top surface of the central cone 41-11. A chassis 30 has an opening 30a formed therein through which only an upper portion of the central cone with the closed top of the rotor is projected towards the major surface. The disk table is thus attached to the back side of the chassis.
