Abstract

A beam damper (140) for damping acoustic noise generated by an actuator (110) of a disc drive (100). The beam damper (140) is compressed between a portion of a housing (102, 104) of the disc drive (100) and an actuator motor (126). The beam damper (140) includes a substantially flat platform (148) affixed to a selected one of the housing (102, 104) and an upper or lower pole (134, 154) of the actuator motor (126). A plurality of flex beams (150) extend from the platform (148) at a selected angle and contact the remaining one of the housing (102, 104) and the upper or lower pole (134, 154) to resiliently bias the housing with respect to the actuator motor (126). The beam damper (140) is preferably formed from a sheet of ductile metal which is stamped to form the platform (148) and flex beams (150), after wich the flex beams (150) are bent to the desired angle.
