OBJECTIVE LENS DRIVING DEVICE, AND OPTICAL PICKUP OR OPTICAL INFORMATION RECORDING AND REPRODUCING DEVICE LOADED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To secure a range of adjusting the inclination in the tangential direction of a disk, in an objective lens driving device, without degrading the performance (sensitivity, dynamic range, etc.), of the driving device. SOLUTION: The wire supporting center of a holder is arranged in the direction away from the disk relative to the wire supporting center of a bobbin, and also, a magnetic circuit is tilted in accordance with that inclination.
