ABSTRACT:
The present invention relates to a method and apparatus for cleaning air in a hard disk drive by gathering the air in the upper and lower portion of the disk and discharging it outwardly through the air discharging position in order to maintain an optimum condition of the air space and reduce the error rate of the hard disk drive. There is provided an air cleaning apparatus for use in a hard disk drive including a spindle motor having a stator, rotor and rotating shaft, a plurality of disks mounted on a circumference of the rotor of the spindle motor, in which the air cleaning apparatus includes an upper air guiding mechanism, provided on an upper side of the rotor, for gathering air to a center of the rotor when the rotor rotates, a lower air guiding mechanism, provided on a lower side of the rotor, for gathering air to a center of the rotor when the rotor rotates, and an air discharging portion extending from the periphery of the rotating shaft to a lower exterior for the rotating shaft, so as to discharge the gathered air to the lower side of the rotating shaft.
