PROBLEM TO BE SOLVED: To couple an optical disk and a disk rotating driving motor with each other by moving the disk rotating motor toward the optical disk. SOLUTION: An elevation motor 280 moves an elevation block 273 where a spindle motor 204 is fixed toward the disk 242 along a shaft 274. After the elevation block 273 reaches a prescribed position, a position detector composed of a reflecting member 282 and a photoreflector 283 detects the prescribed position of the elevation block 273 and then the spindle motor 204 begins to be driven to rotate. |
