ABSTRACT:
There is provided a disk drive in which a base lifting mechanism (93) makes a first disk chucking operation to place an optical disk (2) on a disk mount (27) by elevating at least a base (31) to a disk chucking position, lowers the base (31) to an intermediate position between the disk chucking position and a disk releasing position so that a disk rotation driving mechanism (28) spins the optical disk (2) which will thus take another phase, elevates the base (31) to the disk chucking position again, and makes a second disk chucking operation to place the optical disk (2) on the disk mount (27). Thus, the optical disk can positively be chucked onto the disk mount.
