ABSTRACT:
An optical pickup and driving method for an optical disk drive holding an optical disk includes a base, an object lens, and a slider supporting the object lens, where the object lens focuses a light on a recording surface of the optical disk. An optical head section includes the slider, where an air bearing floats the slider generated between the optical head section and the optical disk. Wire suspensions movably support the optical head section with respect to the base. A driving unit drives the optical head section in a tracking direction and a focusing direction. A latching unit selectively securely positions the optical head section at a predetermined distance away from the optical disk preventing the optical head section from colliding with the optical disk.
