Abstract

PURPOSE:To lower a vibrating level of a resonance frequency, to make easy the control of a servo and to position a magnetic head effectively and stably by filling a resin in a rib of an arm with a rib supporting the magnetic head. CONSTITUTION:An arm 2 to which a magnetic head 6 is attached rotates centering a rotating shaft 5 supported through a bearing 10 by a housing 1. According to a calling, writing instructions, the arm 2 is rapidly moved, the arm 2 produces an up-and-down vibration and a twisting vibration. Then, a position change between information positions of the magnetic head 6 and a magnetic head 7, that is, an off-track is produced, but a damping force of a resin 9 filled in the rib of the arm reduces the vibration of the arm 2.
