A disc drive system includes a base with sidewalls, a spindle attached to the base, and at least one disc attached to the spindle. A cover is also included for attaching to the base. The cover and the base form a disc enclosure which encloses the at least one disc, a portion of the spindle, and the actuator assembly. The disc drive system also includes a cover that is the prime acoustical radiator from the disc drive. The cover includes at least one dampening member attached by the adhesive. The dampening member is provided with a cut or slit therein to shift the resonant frequency of the cover. The cut increases area with high value of shear deformation in the adhesive and increases the loss factor.
