Abstract
Approaches to improving actuator settle time by damping vibrations resulting from coil modes, such as with a voice coil actuator in a hard disk drive, include a single-piece damper plate coupled to the voice coil actuator yoke. The damper plate may be a single U-shaped piece of metal that covers the area of the yoke that experiences the maximum strain energy during operation, between the voice coil and the pivot bearing housing.
