摘要： A reflecting mirror and an optical bench are placed on an external jig provided with a mirror holding portion for maintaining the reflecting mirror, and then the reflecting mirror and the optical bench are bonded and fixed, thus obtaining an optical head. An adhesion reference plane for the reflecting mirror is no longer required in the optical bench, thus reducing the size and cost of the optical bench. The mounting precision is high and stable. Further, the reflecting mirror is bonded and fixed at the vicinities of the approximate centers of its two opposed side faces and therefore the variation in orientation of the reflecting mirror due to expansion or contraction of an adhesive is lessened, thus achieving a highly-reliable optical head excellent in environmental stability characteristics.

摘要翻译：反射镜和光学台被放置在设置有用于保持反射镜的反射镜保持部分的外部夹具上，然后将反射镜和光学台架固定并固定，从而获得光学头。在光学平台上不再需要用于反射镜的粘合参考平面，从而减小了光学平台的尺寸和成本。安装精度高，稳定。此外，反射镜在其两个相对的侧面的大致中心附近被粘接固定，因此由于粘合剂的膨胀或收缩导致的反射镜的取向的变化减小，因此实现了高度可靠的光学头部环境稳定性好。

摘要： In the magneto-optical disk recording and reproducing device, a coil 26a, which serves as a magnetomotive force source is located in the peripheral region of the object lens 5a. A yoke 27a that is a magnetic flux inducing means made of magnetic material serves as the object lens holder. According to this magneto-optical disk recording and reproducing device, even if the object lens is displaced in the radial direction of the information recording medium due to the decentering of the information recording medium or the like, the dislocation of the yoke and coil relative to the object lens is inhibited, stable magnetic field strength is maintained, highly precise recording can be realized, and devices having a small size and thin shape can be realized.

摘要： 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.

摘要： An integrated unit in which a light source and a light emitting diode are combined into one component is fixed to an optical bench. Then, relative position adjustment of an objective lens actuator is carried out with respect to the optical bench so that a desired detection signal can be obtained through reflected light from a disk information recording medium and then the objective lens actuator is fixed. The relative position adjustment of the integrated unit is no longer required and it is no longer necessary preliminarily to provide a margin for adjusting the integrated unit. Thus, an optical head can be reduced in size and thickness.
