PROBLEM TO BE SOLVED: To provide a stable optical disk device wherein fluttering is difficult even in a thin optical disk. SOLUTION: The optical disk device for rotating an optical disk 1 around a shaft is provided with a center push part 2 for pushing the vicinity of the center of the first surface of the optical disk 1 in a shaft direction, a periphery push part 3 for pushing the peripheral part of the second surface of the optical disk 1 in the shaft direction, a rotation mechanism 2 for rotating the optical disk 1 in the conically deformed state of the optical disk 1 by the center and periphery push parts 2 and 3, an optical pickup 4 for converging a laser beam in the optical disk 1, and a pick up moving mechanism 6 for moving the optical pickup 5 in the radial direction of the optical disk 1.
