OBJECTIVE LENS DRIVING DEVICE AND DISK APPARATUS HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To achieve a proper operation of an objective lens driving device by securing the condition required for the objective lens driving device. SOLUTION: A disk apparatus is provided with a base having a support shaft and a magnet and a movable part which is supported so as to be capable of freely rotating in the direction around the support shaft and capable of freely sliding with the axial direction and which has a focusing coil and a tracking coil. The movable part is constituted by combining a first member and the second member. The first member is provided with a holder part which holds an objective lens and a supported tube part that is supported by the support shaft. The second member is provided with a terminal winding part which is wound with a terminal part of the focusing coil or a terminal part of the tracking coil and a coil bobbin part. The first member is formed with a material having a higher stiffness and a higher sliding property than those of the second member, and the second member is formed with a non-conductive material having a higher heat-resistant property than that of the first member.
