| Abstract(in English) | Shingled magnetic recording (SMR) scheme is considered to be necessary for extension of areal recording density of hard disk drives. Microwave-assisted magnetic recording (MAMR) also has potential ability in future magnetic recording for ultra-high K_u media. Exchange coupled composite (ECC) media is considered to be advantageous for the reduction in head field, microwave field, and microwave frequency in MAMR process. This study compared the recording characteristics for 2-layered ECC media and 3-layered ECC media through signal recording simulation. The result showed that 3-layered ECC media shows high SNR greater than 19 dB retaining sufficient thermal stability. In this study potentiality in SMR combined with MAMR was also numerically estimated using micromagnetic simulation. Here, three tracks of 530, 200, 950 kbpi linear densities were recorded with partially overlapping the recorded track subsequently. Consequently, 20-nm track pitch maybe allowed that also means 1.27 Mtpi is feasible in SMR with MAMR. |
