Abstract
A hard disk drive includes a spindle, a motor and multiple disks. The motor is attached to the spindle for rotatably turning the spindle along an axis of the spindle. The disks are disposed coaxially along the axis of the spindle. The distance between a first disk and a second disk is greater than the distance between the second disk and a third disk. The distance between the second disk and the third disk is greater than the distance between the third disk and a fourth disk. The first, second, third and fourth disks are located adjacent to each other consecutively.
