Abstract
An upstream spoiler for a hard disk drive (HDD) includes a top fin configured to cover a radial gap between the top fin and a top disk medium of an HDD to inhibit gas/air flow to a top surface of the top disk through the gap. The spoiler may further include a middle fin adjacent the top fin and a mounting structure configured for mounting the spoiler in an HDD, where the top fin extends circumferentially in an upstream direction beyond the middle fin and tapers down toward the mounting structure, thereby inhibiting particulates from entering a space between an HDD cover and the top disk.
