Abstract:
1. A disk apparatus comprising: a head for performing recording and/or reproduction of data to and from a disk, and a head support mechanism including a slider having the head attached thereto, a slider holding plate for holding the slider, a pair of substrates each having a piezoelectric element attached thereto, a pair of elastic hinges for connecting the slider holding plate and the pair of substrates, and a dimple for supporting the slider holding plate such that the slider holding plate is rotated in a pitch direction, a roll direction, and a yaw direction; wherein each of the piezoelectric elements is integrally formed of a first element provided with first and second electrodes on both planes of a first piezoelectric section, and a second element provided with third and fourth electrodes on both planes of a second piezoelectric section, with the second electrode and the fourth electrode being placed facing each other, wherein a driving voltage is loaded on the first and the third electrodes, and a ground voltage is loaded on the second and the fourth electrodes to make contraction and/or expansion of each of the piezoelectric sections of the pair of piezoelectric elements, and wherein the slider is rotated around the dimple in the yaw direction by contraction and/or expansion of at least one of the piezoelectric elements.
