Abstract
Embodiments of the invention provide a disk drive capable of reducing vibrations of a disk generated by an airflow produced as the disk rotates. In one embodiment, a disk drive comprises: a rotary magnetic disk, a base for housing the magnetic disk, a top cover for closing the disk in the base to form an enclosure, a circulating filter arranged externally of the magnetic disk to trap dust within the enclosure, and an airflow guide for guiding an airflow which flows out of the circulating filter more to the center side than to the outer edge portion of the magnetic disk. Further, a shut out portion is provided in the vicinity of the outer edge portion of the magnetic disk to shut out an airflow which flows out in the vicinity of the outer edge portion.
