A data storage device includes a baseplate (10), a head stack (50), a disk stack (90), a spindle motor (80) first damper (20) and second dampers (30). The head stack is received in the baseplate with the second damper underlying between the head stack and the baseplate. The disk stack combined with the spindle motor is received in the baseplate with the first damper underlying between the disk stack and the baseplate for absorbing vibration and improving dynamic head loading property of the data storage device.
