マスター媒体のパターン形状がビット転写特性に及ぼす影響

抄録

  In this study, the bit printing characteristics of line and space (L/S), checkerboard, and dot patterns were compared in experiments. The results indicated that the peak-to-peak values of the MFM output of L/S, checkerboard, and dot patterns were almost the same. The optimum printing field for the L/S pattern was the same as that for the checkerboard pattern, whereas the optimum printing field for the dot pattern was lower than those of the L/S and checkerboard patterns. This is because the maximum value of the recording field in the dot pattern was larger than those of the L/S and checkerboard patterns.
