Abstract
A hard disk drive (HDD) having a disk damper and a disk protector. The HDD includes a base member, a spindle motor installed on the base member, a plurality of data storage disks mounted on the spindle motor, an actuator pivotably installed on the base member and moving a read/write head to specified positions over the disks, a disk damper disposed between adjacent disks of the plurality of disks and reducing vibrations of the disks, and a disk protector projecting by a specified height toward the disks form positions of top and bottom surfaces of the disk damper to correspond to outer edges of the disks where data is not recorded. Accordingly, if the disks are deflected due to an external shock, only the outer edges of the disks contact the disk protector, thereby preventing data recording surfaces of the disks from being damaged.
