Abstract
An optical scanning device includes an actuator for displacing an objective lens in a first direction parallel to the optical axis of the objective lens, and in a second direction parallel to a radial direction. The actuator includes at least two electrical coils having wire portions directed parallel to the first direction for generating Lorentz forces in the second direction. Points of application of the Lorentz forces on first and second coils of the two coils are in different positions with respect to each other, viewed in a direction parallel to the first direction.
