Abstract
A flying head assembly for a magneto-optical recording drive includes a first head portion of a nonmagnetic material, and a second head portion mounted in an aperture through the first head portion. The second head portion and aperture define an annular path through the first head portion. A coil for generating a magnetic field is wrapped concentrically around the aperture, either inside or outside of the second head portion. A laser light beam is reflected into the annular path and focused onto a recording medium.
