Abstract
A slider assembly for an optical disc drive comprises a slider body having an aerodynamic surface arranged to fly a design distance from a recording surface of a recording medium when the recording medium is rotated at its operating velocity. An objective lens is supported by the slider and defines a focal point at a fixed position relative to the lens. A microactuator is mounted to the slider body to selectively alter the position of the objective lens relative to the slider body. When the slider is flown the design distance from the recording surface, the objective lens may be selectively moved by the microactuator to selectively alter the position of the focal point relative to the recording surface.
