Abstract
A disk drive including a spindle motor rotating a disk, a pickup unit accessing the disk, a frame where the spindle motor is installed, and a vibration absorber installed on the frame to absorb vibrations due to rotation of the disk, that vibrates in a direction in which an exciting force is offset in horizontal and vertical directions with respect to the frame. Thus, as the vibration absorber vibrates in response to vibration of the frame, in a direction to offset the vibration if the frame, the vibration of the frame can be reduced.
