Upstream spoiler with integrated crash stop
Approaches for a single part that comprises an upstream spoiler and a crash stop for use within a hard-disk drive (HDD). The integrated upstream spoiler and crash stop has one or more wings which diverts and reduces the flow of air, resulting from the rotation of the magnetic-recording disks within the HDD, from a magnetic-recording head of the HDD. The integrated upstream spoiler and crash stop has a structure that also prevents the actuator from moving beyond a particular location. After the integrated upstream spoiler and crash stop has been affixed within the HDD, the one or more wings may be rotated between the one or more magnetic-recording disks into a desired position.
