PROBLEM TO BE SOLVED: To enable centering regardless of the size of a disk-like recording medium, and to facilitate the handling of the disk-like recording medium. SOLUTION: A disk centering apparatus comprises a disk placement section 3 that has a disk placement surface 4, where the disk-like recording medium 1000 is placed, and provided with a specified reference point 4a on the disk placement surface; and a plurality of disk centering sections 10 that press the outer periphery end of the disk-like recording medium while at least three of them are provided in the radial direction with the reference point of the disk placement surface as a center. Each disk centering section can be moved between a centering position for centering the disk-like recording medium in contact with the outer periphery end of the disk-like recording medium placed on each disk placement surface, and a standby position outside the centering position with a reference point as a reference. The centering position is at the same distance from the reference point in the radial direction with the reference point as a center. COPYRIGHT: (C)2005,JPO&NCIPI
