ABSTRACT:
An optical head has a stationary optical system and a movable optical system. The stationary optical system includes a semiconductor laser located in a holding member with an opening, and a beam splitter for guiding light emitted from the light source, to the outside of the holding member through the opening. The sheet member contacts both the beam splitter and that portion of the holding member which surrounds the opening thereof, thereby sealing the opening. Further, the holding member is movably secured to the frame of the movable optical system.
