Abstract
An optical storage device including a carriage mounted on a base so as to be reciprocatable in a given direction; a driving mechanism for moving the carriage, the driving mechanism including a first coil fixed to the carriage and a first magnetic circuit mounted on the base; an objective lens for focusing a light beam output from a light source onto an optical storage medium; and a lens holder for holding the objective lens. The optical storage device further includes a conductive elastic support member for movably supporting the lens holder relative to the carriage, the conductive elastic support member having a first end fixed to the carriage and a second end fixed to the lens holder; and a flexible printed circuit board electrically connected to the conductive elastic support member and having one end fixed to the carriage. A second coil is fixed to the lens holder, and is electrically connected to the conductive elastic support member. A second magnetic circuit is fixed to the carriage so as to face the second coil.
