Estimating the term…
A head actuator that positions a head to perform information recording or playback on a computer readable storage medium, has a voice coil flanked by magnets. Through the voice coil a drive current flows and a damper to fit in a space between the voice coil and one of the magnets is formed on at least a portion of the voice coil. The head actuator vibration is controlled to achieve a more compact information storage apparatus and high-density recording. For example, on a voice coil (51) of a head actuator (20), a damping material (71) consisting of single layer viscoelasticity is formed along one lap of the voice coil (51). The damping material (71) is a single layer to not take up dimensions in the thickness direction, and, while pursuing making the apparatus more compact, it is possible to hold down vibration generated by the actuator (20).
