通过改变热辅助磁记录系统中的晶粒几何形状避免超顺磁陷阱

Avoiding superparamagnetic trap by changing grain geometries in heat-assisted magnetic recording systems
摘要：
A data storage medium for perpendicular recording has a substrate and a ferromagnetic layer on the substrate for storing data bits. The ferromagnetic layer has a plurality of elongate grains of magnetizable material extending perpendicular to the substrate which form magnetic domains representative of data. Each magnetic domain is separated from adjacent magnetic domains by a bit edge domain wall region. Each elongate grain has a perpendicular height that is greater than a width of the bit edge domain wall region.
摘要（中）：

用于垂直记录的数据存储介质在衬底上具有用于存储数据位的衬底和铁磁层。 铁磁层具有垂直于衬底延伸的多个可磁化材料的细长晶粒，其形成代表数据的磁畴。 每个磁畴通过位边缘域壁区域与相邻的磁畴分离。 每个细长的颗粒具有大于位边缘畴壁区域的宽度的垂直高度。
