COVER MEMBER WITH AIR INDUCTION PORTION AND HARD DISK DRIVE HAVING THE SAME

摘要

A cover member in which an air guide part is formed and an HDD(Hard Disc Drive) with the same are provided to efficiently remove particles on a disc by guiding air movement generated by the rotation of the disc to the outside of the disc. An air guide part(114) is formed in a lower surface of a cover member(112). The air guide part(114), protruded to a surface of a disc(120) for storing data, guides air movement generated by the rotation of the disc(120) to the outside of the disc(120). The air guide part(114) has a shape whose width is gradually broadened from an upstream side end part(114) in which air flows and a downstream side end part(114b) to which air is exhausted according to a rotary direction of the disc(120).
