を特徴とする光学式情報記録再生装置。[Claims for Utility Model Registration] An optical information recording and reproducing device that records, erases, and reproduces data by irradiating an optical disk with a laser beam, comprising: a lens that focuses spot light onto an optical disk; A beam correction flat glass is swingably provided between a light receiving element that receives reflected light from the disk, and a knife edge or the like is used to block a portion of the reflected light reflected by the optical disk to adjust the amount of inclination of the optical disk. The beam correction flat glass is detected as a change in the amount of light received on the light-receiving element when the light is detected, and the beam correction flat glass is swung based on the detection signal so that the laser beam is perpendicularly irradiated onto the optical disk surface. An optical information recording and reproducing device.
