Abstract
An improved actuator support structure includes a centerpole member having an opening or void disposed at a middle region. The opening improves the rise time of the actuator without diminishing the flux density within the centerpole member. Additional openings are disposed in the centerpole member along opposite sides of the first opening. These additional openings are calculated to optimize the flux density within the centerpole member by slightly restricting the area of the centerpole where the magnetic flux flows.
