摘要： A system and apparatus for reducing flutter in disk drive spoilers positions the center of mass of the mean aerodynamic section of the spoiler at or ahead of the quarter-chord location nearest the leading edge of the spoiler. A balance weight may be formed in or attached to the spoiler. The center of gravity is located no farther back from the leading edge than one quarter-chord in a direction of the flow field. Alternatively, the spoiler trailing edge is lightened by making the trailing edge more porous or thinner than other sections of the spoiler.
摘要翻译：用于减少磁盘驱动器扰流器中的颤动的系统和装置将扰流板的平均空气动力学部分的质心位于最靠近扰流板前缘的四分之一弦位置之前或之前。平衡重可以形成在扰流器中或附着于扰流板。重心位于前缘的距离不比流场方向上的四分之一弦更远。或者，通过使后缘比扰流板的其它部分更多孔或更薄，减轻了扰流板后缘。

摘要： Embodiments of the present invention prevent a magnetic disk drive from increasing in size and in manufacturing cost and reduces a positioning error of a magnetic head. An embodiment of a magnetic disk drive in accordance with the present invention includes: a disk-shaped magnetic disk that is rotated and driven; a magnetic head that reads and writes information to and from the magnetic disk, an arm that supports and moves the magnetic head; a spoiler that is close to a disk surface and extends in a radial direction of the disk; and a cabinet that houses these parts. The spoiler is disposed closer to an upstream side in a rotational direction of the disk than the arm and has a flow rate suppressing clearance positioned in a central portion in a peripheral direction of the spoiler, opened to both sides in an axial direction, and formed in a shape elongated in a radial direction of the disk.
摘要翻译：本发明的实施例防止了磁盘驱动器的尺寸和制造成本的增加，并降低了磁头的定位误差。根据本发明的磁盘驱动器的实施例包括：旋转和驱动的盘形磁盘; 从磁盘读取和写入信息的磁头，支撑并移动磁头的臂; 扰流器，其靠近盘表面并沿盘的径向方向延伸; 和一个装有这些部件的橱柜。该扰流板配置在比臂更靠近盘的旋转方向的上游侧，并且具有位于扰流器的周向的中心部分中的沿轴向两侧开口的流量抑制间隙，并形成在圆盘的径向方向上延伸的形状。

摘要： A sickle-shaped disk drive spoiler for reducing turbulence of airflow in a hard disk drive is provided. The sickle-shaped spoiler includes a body portion for directing airflow generated by a rotating disk, the rotating disk comprising an inner diameter and an outer diameter and wherein the body portion of the spoiler directs airflow away from the outer diameter of the disk and wherein the body portion is curved to substantially mirror the outer diameter of the disk. The sickle-shaped spoiler also includes a first end portion for gradually directing airflow away from the body portion and towards the inner diameter and a second end portion for gradually directing airflow towards the body portion and towards the inner diameter.
