摘要： Provided are a head stack assembly (HSA) with reduced off-track, a hard disk drive including the HSA, and a method of reducing the off-track of the hard disk drive. The HSA includes a swing arm rotatably mounted on a base member of a hard disk drive (HDD); a connecting plate coupled to a front edge of the swing arm; a suspension coupled to the connecting plate to vibrate finely; a pair of hinges disposed on both sides of a center line of the suspension to connect the connecting plate to the suspension; a piezoelectric material layer including a piezoelectric material which is disposed on only one hinge of the pair of hinges, wherein the hinge is closer to a center of a disk in the HDD than the other is; and a head slider that is a recording or reproducing medium of data mounted on the front edge of the suspension.
