ABSTRACT:
A disk chucking device and a disk driving device having the same are disclosed. The disk chucking device may include: a chuck base, on which a boss is formed; chuck chips inserted in the chuck base in a manner such that the chuck chips protrude out from the chuck base; an elastic member, which elastically supports a pair of adjacent chuck chips towards an outer side of the chuck base; and a protrusion portion, which is formed on a bottom of the boss, and which supports the elastic member. The disk chucking device can improve the environment of the elastic members that support the chuck chips, to improve the alignment between the rotation centers of the disk and the chuck base.
