摘要： Provided is a compact inexpensive optical disk drive adaptable to high-density optical disks and having an improved stationary optical unit. The storage device has a first light path and a second light path defined therein. Along the first light path, laser light emanating from a laser light source is passed through a collimator lens and a beam splitter and routed to a movable optical system that is movable on an optical disk. Along the second light path, light reflected from the optical disk and returned from the movable optical system is split into a plurality of rays by the beam splitter, and one of the rays is routed to a sensor via a servo unit and a condenser. An angle at which the second light path meets the first light path is 90nullnullnullnull where null denotes a positive number. At this time, a chassis of the storage device is die-cast, and a stationary optical unit having the first and second light paths defined therein is formed as an integral part of the die-cast chassis at an end of the chassis.
