摘要
A concept of exchange-coupled magnetic layer is presented for the heat-assisted magnetic recording medium. Magnetic layers with different Curie point (T-C) and similar coercivity (H-c) are stacked via exchange coupling. H-c of the double layer changes abruptly at near T-C of one of the layers. This means that the recording temperature can be reduced with little reduction in the thermal stability. A medium consisting of two Co/Pd multilayers was fabricated as this medium. The temperature dependence of H-c of the double layer was similar to that of the expected one by a numerical calculation. (c) 2005 American Institute of Physics.
