摘要： To control the resonance generated in the head assembly and improve property on the head location controlling. A head assembly includes: a slider having a head element; a slider supporting plate for holding the slider; a load beam for holding the slider supporting plate; a support projection which is arranged on the front end part of the load beam and on which the slider supporting plate is supported rotatably; a drive unit that rotates the slider supporting plate around the support projection; a dynamic vibration absorber arranged on the slider supporting plate, wherein the dynamic vibration absorber is disposed closer to the rear end side of the load beam than the support projection and has vibration freedom in the rotating direction of the slide supporting plate.
