Abstract
A stop and a disc drive with a stop are provided that limit rotation of a rotary actuator, which moves laterally between an upper magnet bonded to an upper plate and a lower magnet bonded to a lower plate. The stop includes a spacer core that has an upper portion for contacting the upper plate, a lower portion for contacting the lower plate, and a middle portion having a recessed surface. A stop sleeve is press fit to an upper press-fit surface on the upper portion and a lower press-fit surface on the lower portion. The stop sleeve and the recessed surface together define a deflection space.
