Abstract: A suspension includes a load beam, a flexure including first and second outriggers, and first and second damper members. The first outrigger is formed to oppose the first surface and across the first opening. The second outrigger is formed to oppose the first surface and across the second opening. The first damper member is attached to the first outrigger at the first opening and the first surface. The second damper member is attached to the second outrigger at the second opening and the first surface. An edge portion of the first opening and the first damper member are spaced apart and an edge portion of the second opening and the second damper member are spaced apart.
