An actuator device, an optical disk device and an information playback device comprising: an objective lens for focusing a light on a recording and/or playback face of a recording medium; a lens holder for holding the objective lens; a suspension for elastically supporting the lens holder; and an actuator base for supporting the suspension. The lens holder has a portion on the opposite side in the optical axis of the objective lens with respect to the actuator base.

Actuator device, optical disk device, and information playback device

An optical fiber module for facilitating changing part of an existing electrical signal transmission system to an optical transmission system. The fiber module includes an electric connector, a laser diode (LD) semiconductor IC, an LD module, a photodiode (PD) semiconductor IC, a PD module, an optical connector, a printed circuit board, a cover, and a shielding portion. In one embodiment, the printed circuit board has a constricted portion between first and second areas of the cover. In another embodiment, the circuit board is flexible and can be folded at a central portion. The optical fiber module is easily attachable and detachable from the outside of a computer without requiring a mother board to have optical fibers mounted thereon.
