We developed a magnetic-super-resolution overwritable magneto-optical medium. It be arranged an enhanced structure, because a readout layer and overwritable layers are coupled magnetostatically.
Direct overwriting is done by light intensity modulation, and readout uses the magnetic-super-resolution method. When the length of a recording mark is short, the carrier-to-noise-ratio is high and the erasability is low in comparison with those of a conventional medium.
