摘要：

A perpendicular medium comprising two distinct magnetic layers is described. One layer has a granular structure with isolated. exchange-decoupled grains and the other is a continuous. exchange-coupled layer. In the combined structure domain wall movement is restricted and reversed grains within written bits are eliminated. The S/N ratio is improved compared with single layers of either type alone.
