Abstract
A hard disk drive damper plate comprises a planar main body having a generally rectangular cross-section and a splitter portion extending away from the main body in a radial direction. The splitter portion operates to disrupt vortex shedding corresponding to secondary gas flow associated with the planar main body. Various embodiments involve the length, thickness, and shape of the splitter portion, as well as how much of the planar main body may be provisioned with such a splitter portion.
