Abstract
A turntable device and a disk driving device having the same are disclosed. The turntable device, for detachably securing a disk, may include: a centering part, in an inner perimeter of which slots are formed along a circumferential direction that provide an elastic force; and a base, on which a conical extension part is formed that is configured to slidably support an inner perimeter of the centering part. The turntable device can improve alignment between the centers of rotation of the motor and the disk, even for high-speed rotations.
