Abstract:
1. A disk drive, comprising: an enclosure; a disk mounted to the enclosure for rotation relative thereto, the disk having a surface with tracks; an actuator having a head and mounted to the enclosure for moving the head relative to the disk such that the head reads information from and writes information to the tracks on the disk; a spoiler mounted to the enclosure adjacent to the disk, the spoiler extending radially with respect to the disk and parallel to the surface of the disk, the spoiler having a leading edge, a trailing edge downstream from the leading edge, lateral side edges between the leading and trailing edges, a chord length extending in a direction of an air flow field between the leading and trailing edges, and a center of gravity located along the chord length at a position that is no more than approximately one-fourth of the chord length from the leading edge; and a porous trailing portion is located on and extends from the trailing edge toward the leading edge, and the porous trailing portion causes the center of gravity to be no more than approximately one-fourth of the chord length from the leading edge.
