Abstract:
An optical recording/reproducing apparatus comprising:a light source for emitting divergent optical beams;a collimator lens for converting the optical beams emitted from the light source into parallel beams;an objective lens for converging the optical beams converted to the parallel beams by the collimator lens onto a recording medium;an objective-lens actuator having a mechanism for driving the objective lens in an optical axial direction perpendicular to a recording surface of the recording medium and in a radial direction parallel to the recording surface; anda signal detector for detecting various signals reproduced from the recording medium,wherein elastic members are attached at one end to a lens holder for holding the objective lens and to a fixing member at their other ends to enable the lens holder to move in the optical axial direction and in the radial direction, and the collimator lens is positioned between the objective lens and the fixing member with respect to a direction perpendicular to the optical axial direction and the radial direction.
