摘要：
A magnetic disc drive motor contains a frame; a fixed shaft mounted on the frame and provided with two circumferential grooves; a bearing member including: a plurality of balls disposed in the circumferential grooves; upper and lower roller rings mounted on the fixed shaft through the halls disposed in the circumferential grooves; a pre-loading spring mounted between the upper and lower roller rings; a rotor fixed to one end of the lower roller ring and provided with a loading surface formed in its upper surface; and a motor member mounted below the rotor, wherein the upper and lower roller rings are exposed above the upper surface of the rotor, the roller rings are fitted in center holes of magnetic discs, and inner peripheral portions of the magnetic discs are loaded on a loading surface of the rotor.
