Abstract :
Due to the superparamagnetism, the configuration of magnetic recording system has to be changed in order to enhance the writing capability or to reduce the number of grains per bit. The next target of magnetic recording research is to enable HDD technologies at the areal density of 10 Tb/in2. This work studies the feasibility and the requirement to implement the magnetic recording system at 10 Tb/in2. From the analysis of two possible approaches: the energy assisted magnetic recording (EAMR) on granular media and the bit patterned media (BPM) with EAMR, the simulation based virtual design of magnetic recording system at 10 Tb/in2 is proposed.
