PROBLEM TO BE SOLVED: To provide a disk clamping mechanism enabling the structure thereof to be simplified when an aligning mechanism is provided. SOLUTION: The disk clamping mechanism has an aligning recess 13b disposed in the rotational center of a turntable 13, an aligning mechanism arranged to be moved in the rotational axis direction of a clamper 3 in the rotational center thereof, and an elastic member (compression coil spring 36) for pressing the clamper 3 toward the turntable 13. After the clamper 3 is moved to abut on a disk 2 by a clamper holding member 31, the clamper holding member 31 is moved toward the turntable 13 to compress the elastic member. The aligning member 34 is moved together with the clamper holding member 31 toward the turntable 13, and projected from the clamper 3 toward the turntable 13 by the compression of the elastic member to engage with an aligning recess 13b.
