Patent ID: 7006335

Claim:
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 the slider is rotated around the dimple in the yaw direction by the contraction and/or expansion of at least one of the piezoelectric elements; and wherein the position of the dimple either coincides with a center of gravity of a portion including the slider holding plate and the slider which is rotatable around the dimple as a rotating axis, or is located between the center of gravity of the portion and the head.
