Optical pickup apparatus for optical disk drive and having a flexured floating slider

摘要

An optical pickup apparatus for an optical disk drive records or reproduces data on or from an optical disk, includes an optical head section including an object lens focusing an incident light on the optical disk, a slider on which the object lens is mounted, wherein the slider floats over the optical disk by an air bearing generated between the optical disk and the slider, a bobbin on which the slider is mounted, and a flexure disposed between the slider and the bobbins elastically supporting the slider. A driving unit drives the slider in a tracking direction and a focusing direction. In the above construction, the slider floats over a recording surface of the optical disk due to an air bearing and a near field between the object lens and the optical disk can be controllably maintained.
