Piezoelektrischer Aktor und Vorrichtung zur Informationsspeicherung

A piezoelectric actuator (200) includes a center body (200a) and two spiral arms (200b), the two arms (200b) being entirely in rotation symmetry and nonlinear symmetry. Such a piezoelectric actuator (200) can obtain large displacement at low voltage, be small-sized and lightweight, and be low in man...

More Information
Summary:A piezoelectric actuator (200) includes a center body (200a) and two spiral arms (200b), the two arms (200b) being entirely in rotation symmetry and nonlinear symmetry. Such a piezoelectric actuator (200) can obtain large displacement at low voltage, be small-sized and lightweight, and be low in manufacture cost and accordingly an information storage apparatus in which such a piezoelectric actuator is incorporated can be small sized, lightweight, and have a small inertia moment during head driving and a high recording density.
