A disk fixing apparatus to fix a disk onto a spindle motor in a hard disk drive (HDD). The apparatus includes a coupling hole, in which a coupling portion to fix the disk fixing apparatus onto the spindle motor is inserted, on a center portion of the disk fixing apparatus, and an attaching portion, to which the disk is attached on an outer portion of the disk fixing apparatus. The attaching portion includes an attaching surface extending in a vertical direction so that a part of an inner circumferential surface of the disk can be attached to the attaching surface and/or an attaching surface facing an upper surface or a lower surface of the disk and extending in a horizontal direction so that a part of a non-recording region on the upper surface or the lower surface of the disk can be attached to the attaching surface. Thus, the stress applied to the disk can be reduced and the deformation of the disk can be reduced, and thus, changes in floating height of the head slider can be minimized. Therefore, the recording and reproducing performances of the magnetic head can be improved, and the recording density of the disk can increase.
