An actuator of a magnetic disk has a laminated construction of piezoelectric flat sheet in which there are two polarized regions separated by a non-polarized region and the polarization direction and the direction of applied magnetic fields are the same as the thickness direction of the piezoelectric flat sheet. The actuator is fixed in such a manner as to bridge the top surfaces of the suspension and suspension-supporting member of the magnetic disk, and is coated with a resin material. The actuator enables vertical vibrations and dust generation which occur in association with the movement of the supporting member to be reduced and the accuracy of head positioning to be improved.
