Abstract
A flying optical head assembly for a magneto-optical data storage device includes a slider body mounting an optical element having a narrowed optical aperture extending through a location of the slider body, a recessed region surrounding the location passing the optical aperture, a magnetic pole sheet layer for heat dissipation and reduced magnetic reluctance formed in the recessed region and having an insulation layer and an opening for the optical aperture, and a magnetic bias coil formed on the insulation layer and surrounding the narrowed optical aperture. When formed of electrically conductive material, the sheet layer includes at least one radial slot for preventing a single turn short circuit in direct proximity to the coil. Multiple slots are preferred for bonding and to reduce eddy currents.
