Abstract: A head driving device includes an actuator assembly driving a head member in a width direction of tape. The head driving device includes a first end support beam, a second end support beam, a first skew driving piezoelectric unit, and a second skew driving piezoelectric unit. The first end support beam is arranged between a first end portion of the head member in a length direction and a base member. The second end support beam is arranged between a second end portion of the head member in the length direction and the base member. The first skew driving piezoelectric unit and the second skew driving piezoelectric unit drive the head member around the Z-axis.

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.
