摘要

热辅助磁记录(HAMR)最初是在20世纪90年代提出的，以实现不受超顺磁性限制的存储密度。HAMR的关键是找到一种有效的近场传感器，可以与附近的磁记录杆一起工作。一个集成的HAMR头现在已经被证明可以在高矫顽力FePt介质上以50 nm的磁道宽度和~ 240 Gb/in2的面密度进行记录。

The road to HAMR

Heat assisted magnetic recording (HAMR) was initially proposed in the 1990's to achieve storage densities not limited by superparamagnetism. The key to HAMR has been to find an efficient near field transducer that can operate with a nearby magnetic recording pole. An integrated HAMR head has now been demonstrated which can record at a track width of 50 nm and an areal density of ∼240 Gb/in2 on high coercivity FePt media.
