Numerical investigation of thermal problems in HAMR system

The paper numerically investigated two thermal related problems in heat assisted magnetic recording: the dependence of the recorded mark width on the laser power and the temperature distribution and changes with time in lubricant layer at the condition without or with the heat sink layer. The result...

Beschreibung
Zusammenfassung:The paper numerically investigated two thermal related problems in heat assisted magnetic recording: the dependence of the recorded mark width on the laser power and the temperature distribution and changes with time in lubricant layer at the condition without or with the heat sink layer. The results show that the mark width increases as the laser power increases and heat sink layer helps to reduce temperature in lubricant layer.
