Abstract
Approaches to improving head positioning accuracy in a hard disk drive, by reducing air pressure fluctuations that would otherwise cause unwanted coil torsion in a voice coil actuator, include a voice coil actuator having a streamlined structure configured to affect the flow of air acting upon a coil-supporting arm. The streamlined structure comprises an upper surface and a lower surface, where the upper surface is sloped downward toward the lower surface and the lower surface is sloped upward toward the upper surface.
