ABSTRACT:
An objective lens actuator is provided with an objective lens holder and a tilting coil that drives the objective lens holder in a tilting direction. The tilting coil is inclined with respect to the horizontal direction, so that a rotation center when the objective lens holder is driven in the tilting direction, is located on extension lines of sides that effectively contribute to driving the objective lens holder in the tilting direction by interaction between a magnetic field formed by a magnet and current that is supplied and flows in the coil among sides of the tilting coil.
