MEKANISME PENOPANG BONGGOL DAN AKTUATOR PIESOELEKTRIK FILM TIPIS

摘要

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 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.
