摘要:
An optical element driving apparatus includes a holder that holds a plurality of switchable optical elements for focusing light on a recording medium, a resiliently deformable supporting unit that supports the holder, a focusing driving unit that drives the holder in a direction of optical axes of the optical elements, and a tracking driving unit that drives the holder in a tracking direction perpendicular to the direction of the optical axes. The switching of the optical elements is performed by moving the holder by means of the tracking driving unit, so as to select one of the optical elements that focuses light on the recording medium.
