Abstract
The present invention relates to a spindle motor mainly used for an apparatus for driving a disc, which can increase the capacity of recorded information and the information transmission speed while reducing the size and thickness of the apparatus. This spindle motor corrects the balance of a structurally unbalanced chucking portion, and reduces the shaft deflection of a motor, non-uniform rotations, the inclination of a disc relative to a head, and the surface deflection of a disc loading portion.
