磁気転写及び磁気ヘッドで記録されたハードディスクの磁化状態

抄録

  The magnetization distribution of a hard disk recorded with magnetic printing and a recording head were compared by utilizing micromagnetic simulation. The servo-signals were modeled with a line and space (L/S) pattern and a checker pattern in this study. The fidelity of recording for L/S and checker patterns were the similar for both methods. As a result, we found that the recording fidelity in magnetic printing was equal to that in head recording though both recording field strength and the gradient in magnetic printing were less than those for head recording. This is because magnetic printing has no recording demagnetization.
