[Claims for Utility Model Registration] (1) A rotating shaft that supports a disk, which is a magnetic recording medium, and a light beam irradiated from an infrared light source juxtaposed in front of the surface to be inspected of the disk, and this light beam is irradiated. a rotatable light flux limiting plate in which an aperture is formed to limit an irradiation surface on the disk to a constant level; a detector for receiving reflected light of the light beam by the disk; and the disk is sequentially determined. An automatic disk inspection device comprising: a control unit that controls rotation of the rotation shaft so as to rotate and move the rotation shaft to the irradiation section of the light beam. (2) The automatic disk inspection device according to claim 1 of the utility model registration claim, wherein a plurality of infrared light sources and a plurality of detectors are arranged on both sides of the disk. (3) An automatic disk inspection device according to claim 1, which is a utility model and is equipped with a moisture meter that monitors the moisture content of the inspection atmosphere and a dry nitrogen supply device that is linked to the moisture meter.
