光磁混合记录是一种采用激光辅助加热磁写入，可以突破铁磁材料超顺磁极限的限制，提高硬盘记录密度的新型高密度磁记录方式。
Hybrid recording is a new kind of high density information storage technology that can break through the super-paramagnetic limit and increase the recording density of hard disk drives (HDD).
因此，记录密度的继续提高，很大程度上受限于磁头的写入能力。
Therefore, further increase of magnetic recording density is largely confined by the writing ability of the magnetic head.
