PURPOSE: A bobbin structure of an optical pickup actuator is provided to increase the width of an inner yoke receiving groove of a bobbin and a part of a frame boundary surface, thereby coping with more than a high speed by stable driving features. CONSTITUTION: A square-shaped lens fixing frame(122) integratedly comprises an x-shaped lens setting portion(121) where an objective lens(130) is set on a center. A bobbin fixing frame(123) is integratedly molded by inserting right/left sides of the lens fixing frame(122) into grooves formed on right/left inner sides thereof. Focusing/tracking coils(160,170) are wound on upper/lower right/left sides and the girth of the bobbin fixing frame(123).
