Abstract
A beam damper for damping acoustic noise generated by an actuator of a disc drive. The beam damper is compressed between a portion of a housing of the disc drive and an actuator motor. The beam damper includes a substantially flat platform affixed to a selected one of the housing and an upper or lower pole of the actuator motor. A plurality of flex beams extend from the platform at a selected angle and contact the remaining one of the housing and the upper or lower pole to resiliently bias the housing with respect to the actuator motor. The beam damper is preferably formed from a sheet of ductile metal which is stamped to form the platform and flex beams, after which the flex beams are bent to the desired angle.
