Title: Optical recording/reproducing apparatus

Abstract: An optical recording/reproducing apparatus comprises: a light receiving and emitting device that emits divergent optical beams and detects various signals on a disk; a collimator lens for converting the optical beams emitted from the device into parallel beams; an objective lens for converging the optical beams of the parallel beams onto the disk; and an objective-lens drive for driving the objective lens in a focusing direction perpendicular to a recording surface of the disk and in a radial direction parallel to the recording surface. The objective-lens drive is supported by suspensions attached at one end to a lens holder for holding the objective lens and to a fixing member at their other ends. The collimator lens is positioned between the objective lens and the fixing member. Thus, the optical recording/reproducing apparatus can be reduced in size and can improve the strength of the suspensions for supporting the objective-lens drive against disturbance vibration or impact caused when the optical recording/reproducing apparatus is dropped.
