Abstract
Embodiments of the present invention restrain the head position accuracy from degrading due to torsional vibration of a head supporting unit. According to an embodiment of the invention, an actuator has a twisted carriage arm. A suspension is tilted in accordance with the twist of the carriage arm. When the carriage arm and the suspension torsionally vibrate, the vibration direction tilts against the normal direction of a recording surface in accordance with the twist. This technique decreases a peak value of off-track displacement that is caused by a head slider and is dependent on relationship between a skew angle and a torsional vibration direction.
