According to one embodiment, a data storage device has a base deck and a cover mounted on the base deck. A Voice Coil Motor (VCM) is mounted on the base deck below the cover. The VCM has a lower magnetic plate mounted on bosses extending from the base deck and an upper magnetic plate mounted on the lower magnetic plate. A damper is positioned between the upper magnetic plate of the VCM and the cover. The damper comprises a plurality of contact points distributed across the upper magnetic plate. The contact points extend between the upper magnetic plate of the VCM and the cover. Alternatively, a damper is positioned between the lower magnetic plate of the VCM and the base deck. The damper comprises a plurality of contact points distributed across the lower magnetic plate. The contact points extend between the lower magnetic plate of the VCM and the base deck.
