Abstract
A movable enclosure contains optical components, such as an objective lens, a semiconductor laser, a mirror, and a photodetector. The movable enclosure is supported by a fixed member via a plurality of wires that are positioned in parallel. This construction allows the movable enclosure to move in a tracking direction and a focusing direction. The plurality of wires are insulated from one another to be also used as power-supplying lines and signal lines for the semiconductor laser and the photodetector.
