Abstract
A method of using laser light to access a magneto-optical disc utilizes first and second objective lenses, the second objective lens being mounted in a light channel of a slider having a primary planar surface that flies over the surface of the magneto-optical disc. The laser light is directed through the first and second objective lenses that focus the laser light onto the surface of the magneto-optical disc. Focus of the laser light is maintained solely by moving the first objective lens in an axial direction with respect to the magneto-optical disc, the first objective lens being mounted to an actuator.
