Abstract
A data storage disk capable of limiting a crack from extending during operation is provided. The data storage disk has a center, an outer edge, an inner edge, and at least one slot. The slot is disposed between the outer edge and the inner edge. When a crack occurs in the disk, the slot disperses a stress which forces the crack to extend. Therefore, the slot hinders extension of the crack to prevent the disk from break.
