OBJECTIVE LENS DRIVING DEVICE

PROBLEM TO BE SOLVED: To provide an objective lens driving device capable of making high- speed response, having the improved vibration characteristic of a track direction. SOLUTION: Focus springs 4a, 4b, 4c and 4d are provided with notched parts 12af, 12ap, 12bf, 12bp, 12cf, 12cp, 12df and 12dp between movable member slits 3a, 3b, 3c and 3d and an FPC 11, and between track holder slits 13a, 13b, 13c and 13d and a substrate 10. Because of the presence of the notched parts between the movable slit 3 of the focus spring 4 and the FPC 11, and between the track holder slit 13 and the substrate 10, the secondary resonance of the vibration frequency characteristic of the track direction is suppressed, and high-speed response is made.
