The optical flying head (OFH) was designed and fabricated for implementation of the first surface magneto-optical (MO) recording technology. The OFH structure for integration with the small ball lens and double-layer microcoil has been developed. An objective lens and microcoil thinned by 30 μm were attached to the OFH. It was found that the OFH could fly above the disk media at a more than 100 nm flying height with a 2 μm lens bottom-to-disk cover layer gap; and the microcoil had a 20 $\Omega$ resistance and 160 nH inductance as measured up to 100 MHz. The performances of the OFH and microcoil were adequate to demonstrate the feasibility of the magnetic field modulation (MFM) MO recording technology.
