Abstract
A method and apparatus for magneto-optical storage and access of data. The apparatus comprises a flying magnetic head, wherein the flying magnetic head comprises: a slider that flies over a magneto-optical disc during read and write operations performed on a magneto-optical disc; a magnetic coil fixedly attached to the slider, the magnetic coil defining a channel through the slider, the magnetic coil and the slider forming a smooth, planar surface parallel to a surface of the disc during read and write operations; and a first objective lens fixedly attached in the channel such that a surface of the first objective lens is parallel to the smooth, planar surface.
