US 7,453,667 B2 · Hard disk drive, hard disk damper, and method for the same

Abstract

A hard disk drive, hard (HDD) disk damper, and method for the same. The HDD may include 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 to move a read/write head to a predetermined position on each of the disks, and a disk damper disposed between adjacent disks of the plurality of disks reducing vibrations of the disks. The disk damper has at least one groove, having a predetermined depth from an outer circumferential surface thereof, extending a predetermined length along the circumference of an outer edge thereof. Accordingly, a disk damper of the present invention can reduce vibrations of disks and protect data recording surfaces of the disks from external shocks.
