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 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.

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： An optical head includes the following: a light beam separator (35) that includes substantial interference regions for light that is reflected from an information recording medium and travels in a straight path and ±first-order diffracted light produced by information tracks of the information recording medium, and diffracts each of plural light beams in regions (32a, 32b) of the substantial interference regions, where the amount of light is changed by a change in the relative angle between the information recording medium and the objective lens and by a shift of the objective lens in the radial direction of the information recording medium; a light-receiving element (36a, 36b) for receiving the light beam that is reflected by the information recording medium and separated by the light beam separator (35); and an arithmetic circuit that corrects a value of an electrical signal detected by the light-receiving element (36a, 36b) in accordance with a radial position signal corresponding to the amount of shift of the objective lens in the radial direction of the information recording medium, and detects the relative angle between the information recoding medium and the objective lens.
