Approaches for integrating an upstream spoiler with a particle filter in a hard-disk drive (HDD). According to an approach, a single part may comprise an upstream spoiler and an opening. The single part has a structure which enables an airborne particle filter to be positioned over or within the opening. The airborne particle filter, which covers the opening, has a curvature that follows the curvature of a shroud. When the upstream spoiler diverts a flow of air, which circulates within the enclosure when the magnetic-recording disk is rotating, from the magnetic-recording head, the upstream spoiler creates an area of relatively greater pressure. Air in the area of greater pressure flows through the airborne particle filter to an area of relatively lesser pressure, thereby removing airborne particles within the enclosure of the HDD. Alternately, the airborne particle filter may be positioned within slits present in the shroud and the upstream spoiler. |
