PROBLEM TO BE SOLVED: To provide a disk clamping mechanism which stably maintains centering even when it is used at high speed revolution by solving a skid caused by centrifugal force during high speed revolution resulting from the mass eccentricity of a disk. SOLUTION: In the state where a flange part 5a of a clamper 5 is separated from a support angle 6, a projecting part 5c of the clamper 5 is attracted by a magnet 7 fixed to a turntable 4. A disk pressure part 5b of the clamper 5 holds the disk 9 together with a skid stopping member 8 fixed to the turntable 4. A center hole 9a of the disk 9 is pressed in a radial direction by a centering lug 4d of the turntable 4 without contacting the base part of the center guide part 4 of 4 of the turntable.
