Abstract

PURPOSE:To offset the inertia mass in the feeding direction of an actuator by the inertia mass of a balancer and to reduce the effect against the inclination of a device and the impact from the external part by combining the balancer having equivalent mass with that of a head arm with the head arm via the annular belt turning together with a pulley on the outer periphery of a pair of pulleys. CONSTITUTION:At the position where a belt 11 is opposed to a head arm 6, the balancer 12 having the equivalent mass with that of the head arm 6 including the part movable with the head arm 6 is fixed and supported slidably in parallel to the longitudinal direction of a magnetic circuit 3 by the guide shaft 13 fixed in parallel to a guide shaft 4. When a control current is passed to a head feeding coil, the head arm 6 is subjected to linear feeding in the longitudinal direction of the magnetic circuit 3 and the balancer 12 combined with the head arm 6 via the belt 11 is subjected to linear feeding in reverse direction to the moving direction of the head arm 6 along the longitudinal direction of the magnetic circuit 3 simultaneously. The inclination resistance and impact resistance of a head feeding mechanism can thus be improved.
