A motor includes a shaft that serves as a rotation center when a rotor is rotated with respect to a stator, a bearing that supports the shaft in a circumferential direction of the shaft, a thrust bearing that supports one end of the shaft in a thrust direction of the shaft, a magnet that is fixed to the rotor and alternately magnetized to different poles in a rotational direction of the shaft, a core that is fixed to the stator and disposed to face the magnet in a radial direction of the shaft, a coil that are wound around the core, and a magnetic shield that shields leakage flux leaking from the magnet to the coil. A magnetic center of the core is offset from a magnetic center of the magnet in the thrust direction, so that the shaft is attracted to the thrust bearing.

A structure for securing a spindle motor (15) supported on a motor substrate (32) to a chassis (13). The motor substrate (32) and the chassis (13) are coupled by at least three coupling sections (33). At least two of the coupling sections (33) are fixed support members (33a) which hold and space the motor substrate (32) and the chassis (13) from each other at a prescribed distance. The remaining coupling section is an adjusting support member (33b) that holds the motor substrate (32) and the chassis (13) from each other at a variable distance. Rigid holding means is incorporated in the adjusting support member (33b) and holds the motor substrate (32) and the chassis (13) so that the motor substrate (32) and the chassis (13) remain rigid.
