A head support mechanism includes a slider for carrying a head at least for performing
reproduction of data from a disk, and a holding portion for holding the slider.
The holding portion includes: a first portion including a first piezoelectric element;
a second portion including a second piezoelectric element; a third portion connected
to the first and second portions, the slider being provided on the third portion;
and a fixing portion for fixing the first and second portions. At least one of
the first and second piezoelectric elements is contracted and expanded in a direction
substantially parallel to a surface of the disk, in the presence of an applied
voltage so that the slider provided on the third portion is rotated around a predetermined
center of rotation.
