ABSTRACT:
There is provided an actuator, an optical device, and an optical recording/reproducing apparatus. In the optical device, a first lens is fixed in an optical axis and a second lens, a movable member is supported by a shaft and slidable in an optical axis direction, and a second lens is formed on the movable member. The movable member is moved by interaction between a coil and a magnet.
