描述了一种包括两个不同磁性层的垂直介质。一层具有颗粒结构，其中包含孤立的、交换解耦的颗粒，另一层是连续的、交换耦合层。在组合结构中，畴壁运动受到限制，并且消除了写入位内的反向晶粒。与单独的任一类型的单层相比，S/N比得到改善。
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.
