A disk clamp of a hard disk drive for firmly installing a magnetic disk for storing data at a spindle motor of the hard disk drive, which includes a vertical pressing portion, formed along an edge portion of the disk, for pressing an upper surface of the disk in a vertical direction, a plurality of horizontal pressing portion, formed inside the vertical pressing portion to protrude downward to be inserted between an outer circumference of the spindle motor and an inner circumference of the disk, for pressing an inner circumferential surface of the disk outwardly, and a plurality of screw coupling holes formed inside the horizontal pressing portion, through which screws are inserted to be coupled to an upper end portion of the spindle motor. The horizontal pressing portions are formed at least three positions in a circumferential direction at identical intervals or at four positions at an interval of 90° in the circumferential direction. Thus, when an external impact is applied to the hard disk drive, a slip of the disk is not generated so that the spindle motor is prevented from being damaged.
