ABSTRACT:
A sickle-shaped disk drive spoiler for reducing turbulence of airflow in a hard disk drive is provided. The sickle-shaped spoiler is configured to direct airflow generated by a rotating disk and includes a tapered first end portion configured to direct the airflow toward the inner diameter of the disk and to reduce the airflow on the side of the disk opposing the spoiler.
