摘要： In a laser module holding a semiconductor laser chip and a reflecting surface, to perform positioning on the semiconductor laser chip with high precision, and reduce the period of production, so as to realize downsizing and cost reduction, reflecting surfaces provided on a silicon substrate has a step portion, and the reflecting surfaces are used as reflecting surface for laser emission light and laser chip positioning surface, for high precision positioning. Further, in a laser module which requires a high level power for recording, slopes opposite to side surfaces of the semiconductor laser chip in a lengthwise direction have a step portion, and in wiring of lower electrodes of the laser chip from the bottom of the sink to an upper portion of the silicon substrate, a slope having an angle with respect to the laser chip lengthwise direction is formed as a gentle slope, then wiring is made via the slope, thus mitigating occurrence of migration.

摘要： A laser element assembly used in an optical disk apparatus or others is made up of a laser element for emitting a laser beam and a holder for holding the laser element, and it is required to set the traveling direction of the laser beam accurately to a desired direction when the laser element assembly is incorporated in the optical disk apparatus. In a laser element assembly according to the present invention, the laser emitting surface of the holder is made perpendicular to the traveling direction of the laser beam and is attached to the optical disk apparatus. Thus, the traveling direction of the laser beam can be accurately arranged in relation to a reference plane of the optical disk apparatus. Further, in a method of fabricating a laser element assembly in accordance with the present invention, a laser element is operated so as to emit a laser beam, and a machining operation is performed for the laser emitting surface of a holder in a state that the laser beam is emitted from the laser element, to make the laser emitting surface perpendicular to the traveling direction of the laser beam.

摘要： An optical disk apparatus includes a motor to rotate an optical disk and an optical head to apply light to the optical disk. The optical head includes a light source to emit the light to be applied to the optical disk, and a collimating lens to receive and collimate the light emitted by the light source. The collimating lens has an optical axis. The optical head also includes a support wall to support the collimating lens at a particular position. The support wall is configured to provide a gap between the collimating lens and the support wall to enable the collimating lens to be adjusted from an initial position to the particular position. The adjustment involves at least a movement in a direction that is perpendicular to the optical axis of the collimating lens. The optical head further includes an objective lens that is configured to receive the light from the collimating lens in order to apply the light to the optical disk.
