摘要: In this paper, we propose a method of write current optimization based on the contour graph. The graph is plotted from bit error rate (BER) which obtaining running full combination. process, consider effect to system performance such as protrusion level heads and adjacent-track interference (ATI) recording head following upon amplitude variation duration considered. Increasing overshoot causes transition shift or inter-symbol (ISI). Before selecting current, squeezed measure each. proposed method, first, run combination including amplitude, duration. Then plot between duration, select best that gives widest BER area. Next, three upward edge points On contrary, overshoot, area, overshoot. After that, eight then get 24 sets current. Finally, triplet. We can deduce experimental result better than baseline method. Moreover, observe fixed yields higher However, in unsqueezed mode, contrast because affects more
