Abstract:
1. A disk drive, comprising: a base; a spindle motor coupled to the bottom of the base; a disk coupled to and rotated by a rotational shaft of the spindle motor; an airflow reduction plate coupled inside the base and positioned opposite to and away from a main plane of the disk; and a sidewall section inside the base which is positioned opposite to an outer edge of the disk and has a form along the outer edge of the disk, wherein a first gap between at least one half of a part positioned opposite to the sidewall section in an outer edge of the airflow reduction plate and the sidewall section is smaller than a second gap between the sidewall section and the outer edge of the disk; a mechanism for pushing the airflow reduction plate toward the sidewall section in a direction about perpendicular to and away from a rotational axis of the spindle motor; and a screw penetrating a hole in a tab formed on the outer edge of the airflow reduction plate in a direction normal to a main plane of the airflow reduction plate, wherein the screw is fastened to a screw hole located beyond an outer dimension of the sidewall section inside the base, wherein the mechanism further includes an elastic component for pressing the airflow reduction plate against the sidewall section which pushes the tab between the screw and the hole in the tab.
