An actuator structure includes an arm portion carrying a predetermined number of heads for recording/reproducing information, provided on one side of a rotary shaft, and at least two coil support portions, each of which supports a coil member for moving the heads on recording media, provided on the other side of the rotary shaft relative to the arm portion. Each of the at least two coil support portions extends from either side of a line passing through the head and the rotary shaft, and the at least two coil support portions are formed asymmetrically relative to the line.
