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.
