Control Of Vortex Shedding Associated With A Hard Disk Drive Damper Plate

摘要

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.

主权项

1. A hard disk drive comprising:
a plurality of recording disk media rotatably mounted on a spindle; a head slider comprising a read-write transducer configured to read from and to write to at least one of said disk media; a voice coil actuator configured to move said head slider to access portions of said at least one disk media; and a damper plate interposed between two adjacent disk media and extending in a direction toward the center of said disk media, said damper plate comprising:
a planar main body having a substantially rectangular cross-section, anda splitter portion extending away from said main body further in a radial direction toward said center of said disk media.
