デイスク駆動装置。 In order to prevent the printed circuit board and base from rising in temperature, a radial fan is installed on the outer rotor of the spindle motor, and the printed circuit board in contact with the rotor, which corresponds to the suction part of the fan, is used as a space, and the suction port of the radial fan is In addition, the outer periphery of the printed circuit board space has the effect of a radial fan casing to smooth air flow.
A hard disk drive device characterized by preventing temperature rise.
