Abstract(in English) | Various methods for bit-patterned media were investigated to obtain high areal density recording beyond 2 Tdot/in^2. When the dot density is increased, increased switching field dispersion due to the magnetostatic interaction between the dots restricts the attainable recording density. But it was found that introduction of optimized exchange coupling between the dots or inclined magnetic anisotropy decreased the broadened switching field dispersion. Simulation analysis indicated the possibility of recording of an areal density beyond 2 T dot/in^2 by these methods. Moreover, with 3-layer ECC dot BPM with optimized parameters, it was also found that an areal density of 4 Tdot/in^2 would be realized using shingled recording. |
