摘要： An optical pickup device includes a laser source for emitting linearly polarized light; an objective lens for focusing source light received from the laser source on an optical information storage medium; a photodetector for receiving signal light reflected from the medium for converting the signal light into an electric signal. The photodetector includes at least a photosensor, a planar optical waveguide formed on the photosensor for propagating the signal light therethrough, diffraction grating for diffracting the signal light propagating through the waveguide, and an incidence coupler provided on the waveguide for reflecting the source light emitted from the laser source and receiving signal light obtained through the objective lens from the medium. A plane of incidence including a normal to a surface of the incidence coupler and the optical axis of the source light is formed at an angle range of 5 to 85 degrees to a plane of polarization of the source light having an electric field vector of the optical axis and the source light. Thus, the direction of polarization of the signal light from the medium is also formed at an angle range of 5 to 85 degrees to the plane of incidence for the signal light to thereby detect the presence/absence of information. This reduces the size of the pickup device.

摘要： The present invention provides an object lens actuator in which a tilt of an object lens due to a change of an ambient temperature is inhibited even when a metal member is attached to a resin based securing part. It is desirable to improve quality of writing and playing in a disc drive using the object lens actuator. This is achieved by coupling a metal member having a flat portion and bent portions to a securing part near top ends of the bent portions. The flat portion has a normal in the focusing direction. The bent portions extend in the focusing direction from the respective ends of the flat portion in the tracking direction. The securing part has an opening therethrough in the focusing direction, and in the opening, the metal member and the securing part may be coupled between each outermost two support members in the focusing direction.

摘要： An aspect of the invention provides an optical pickup in which an optical axis is not displaced even if ambient temperature is changed. The optical pickup of the invention has an optical unit and an optical pickup case. The optical unit has a lens member having an optical axis, and the optical axis of the lens member is offset to one side from the center of the optical unit. The optical pickup case holds the optical unit from both sides. A thermal expansion amount of the optical unit is absorbed by compression amounts of a first adhesive and a second adhesive such that the optical axis of the lens member is not displaced when the optical unit is thermal expanded.

摘要： This invention aims at reducing a rolling moment generated in coils mounted to lens holder side face without losing drive forces in a focusing direction and tracking direction in an objective lens drive of an optical pickup device. By shifting a coil line portion near the objective lens of two coil line portions substantially parallel to the tracking direction of the first coil in a direction departing from a lens optical axis, increase and decrease in drive forces generated in right and left first coils when the lens holder is moved in the tracking direction cancel each other so as to eliminate imbalance between the right and left drive forces.
