器固定機構。 A light beam having a plurality of light-receiving areas on the flange surface of a housing housing an optical system that condenses laser light from a light source onto a disk using a condensing system such as an objective lens and receives reflected light from the disk. A photodetector fixing mechanism for an optical head in which a support plate containing a detector and a presser plate disposed in front of the support plate are tightened and fixed using fixing screws,
The support plate is made of a material with higher hardness than the casing, and a protrusion is provided on the inner surface of the support plate, so that when the fixing screw is tightened and fixed, the protrusion touches the flange surface of the casing. A photodetector fixing mechanism for an optical head, characterized in that it is fixed by recessing.
