摘要：
A folding mirror structure comprises a folding mirror, a piezoelectric film and electrodes attached to the surfaces of the piezoelectric film. The folding mirror is used for deflecting a laser beam. The piezoelectric film and electrodes are stacked in an interleaving manner and attached to the folding mirror. The surfaces of the electrodes have particular patterns for compensating the coma aberrations due to the tilt of an optical disc.
