Abstract: A head driving device includes a base member, a head supporting member, a beam member, a piezoelectric unit, and a reinforcement member. The reinforcement member includes a first portion and a second portion. The first portion is arranged between a first end portion in a length direction of a head member and the base member. The second member is arranged between a second end portion in a length direction of the head member and the base member. The reinforcement member allows the head supporting member to move in a direction along a surface of tape and controls the head supporting member from moving in a thickness direction of the head member.

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.
