ABSTRACT:
A disk drive device includes a device stand on which a spindle motor and a device control board are fixedly mounted. The device stand has a motor mounting section which is embossed so that the spindle motor is mounted on the motor mounting section. Fastening members are inserted into the mounting holes which are formed in a stator core and the motor mounting section in such a manner that they are aligned with one another so that, with the fastening members, the circuit board is held between the motor mounting section and the stator core, and the spindle motor is fixedly mounted on the device stand. The circuit board follows the surface of the motor mounting surface being held in close contact with the latter.
