設けたことを特徴とする光情報記録再生装置。 A semiconductor laser is mounted on a gliding body and moved relatively close to the information recording surface of the optical disk by air levitation based on the rotation of the optical disk, and a laser beam is focused and irradiated directly onto the information recording surface in the form of a minute spot. A laser light source is provided, and a diffraction grating that receives and diffracts the transmitted light from the information recording surface irradiated by the laser light source and a light receiving element that receives the output of the diffracted light by this diffraction grating are mounted on the same substrate. What is claimed is: 1. An optical information recording/reproducing apparatus comprising an integrated photodetecting element and an actuator that interlocks the laser light source and the integrated photodetecting element to move them relative to the optical disk.
