在混合记录系统中
记录材料矫顽力依赖于温度
激光可用来降低矫顽力使得仅仅在激光加热的地方磁元反转
本文对混合记录剩余磁场与温场的关系和记录介质热响应进行了研究
结果证实采用高矫顽力的磁记录材料
波导近场热辅助写的技术方案可以用来克服超顺磁极限的限制
大大提高记录密度
是一种很有潜力的技术方案.
In a hybrid recording system
since the coercivity is dependent on temperature
an external laser may be used to locally reduce its value to a point where the field from the magnetic head is sufficient to switch the magnetization;In this paper the relation between the hybrid recording magnetic field and the thermal field
the recording media heat domino effect have been studied
the results indicate that the rectangle waveguide near field heating technology can break superparamagnetic limit and meet the demand of hybrid recording.This is a high potential method and can increase storage density consumedly.
