<p>PROBLEM TO BE SOLVED: To provide a disk device capable of quickly changing a positional relationship around the rotation axis between a disk and a turntable.SOLUTION: When reproduction of information on a disk d is not possible due to mechanical characteristics changed by positional relationship around a rotation axis between the disk d and a turntable 14, chucking by a clamper 15 is loosened in a range where the disk d does not run off from the turn table 14 in a state in which the turn table 14 is rotationally driven, and the rotation of the turn table 14 in this state is braked so as to make the disk d to rotate by inertia, thereby changing the positional relationship around the rotation axis between the disk d and the turn table 14.</p> |
