热辅助磁记录（HAMR）在过去几年中已经成为将磁数据存储推向1 Tb/in/sup 2/甚至更高的面密度的主要候选者之一。使用热辅助写入非常高的各向异性磁介质是一种自然的手段，继续几十年来的范例，按比例增加颗粒磁膜的存储密度的能力。这种方法似乎是完全兼容的扩展性能的垂直记录远远超出其预期的限制，使用环境温度记录。最近的发展表明，HAMR可以利用记录过程中赋予的热能来实现极快的磁切换，而不需要非常高的写入磁头磁场，从而实现性能的进步。
Heat-assisted magnetic recording (HAMR) has emerged in the past few years as one of the leading candidates to carry magnetic data storage toward areal densities of 1 Tb/in/sup 2/ and perhaps well beyond. The use of thermal-assistance for writing very high anisotropy magnetic media is a natural means of continuing the decades-old paradigm for scaling upward the storage density capability of particulate magnetic films. This approach appears to be fully compatible with extension of the performance of perpendicular recording well beyond its expected limits using ambient temperature recording. Recent developments indicate that HAMR may take advantage of thermal energy imparted in the recording process to achieve extremely fast magnetic switching without the need for inordinately high writing head fields, thus enabling performance advances.
