摘要： A record carrier for thermomagnetic recording of information and magneto-optical readout of the recorded information. The record carrier includes a substrate and a recording layer thereon in the form of multi-layers of magnetic and non-magnetic material, the magnetic layers predominately containing cobalt and the non-magnetic layers predominantly containing transition metal. The magnetic and non-magnetic layers alternate, and the overall thickness of the complete multi-layer recording layer is less than 75 nm. Such a recording layer achieves a significant improvement in both thermomagnetic write properties and magneto-optical read properties.

摘要： The addition of Os or Re to the Co layers of a magneto-optical recording medium comprising a Co/X multilayer, where X=Pt, Pd, Au, Ni or Ru, results in a reduction of both the Curie temperature and the magnetization. By virtue thereof, the rewritability of the medium is improved and higher write frequencies can be employed.
