    摘要： An optical pickup having a light-emitting element, an objective lens unit, a reflecting mirror and a light-receiving element, emits a beam onto an optical recording medium and uses a reflected beam to read recorded information. In the objective lens unit, a central part of a surface, facing the light-emitting element, of an objective lens disposed so that an optical axis is substantially aligned with a chief ray of the beam emitted by the light-emitting element, is a transmissive diffraction grating, and a central part of a surface of the objective lens that will face the optical recording medium is a convex mirror which bulges toward the light-emitting element. The reflecting mirror, which is annular and encompasses the optical axis of the objective lens, reflects toward the objective lens the beam from the light-emitting element that has passed through the transmissive diffraction grating and been reflected by the convex mirror. The light-receiving element receives first-order diffracted light, of the reflected beam from the recording medium, diffracted by the transmissive diffraction grating.

    摘要： An optical irradiation apparatus includes: a light-emitting device configured to emit a plurality of light beams whose optical axes extend in a substantially identical direction; a collimator part configured to convert the light beams into parallel light beams; and a light condensing part configured to collect the parallel light beams. The light-emitting device includes a super luminescent diode array in which a plurality of waveguides are provided on a substrate. Each of the waveguides has a light-emitting facet including a light emission point from which an associated one of the light beams is emitted. The light emission points are located in a plane. The plane including the light emission points is orthogonal to a direction of an optical axis of the collimator part.

    摘要： A lens holding member carrying an objective lens is movable and supported by a fixed member via a plurality of supporting members. Each supporting member includes a bent part in its base portion on the side of the fixed member. The bent part is bent in a first direction (focusing direction) and a second direction (tracking direction) that are perpendicular to each another. Each supporting member is shaped so as to make all the principal planes of the supporting member parallel to the second direction. The fixed member includes a concave, which is impregnated with a gel material so that the bent part is covered with the gel material.
