17-4 塗布型 Ba-ferrite テープシステムに適した信号処理方式の検討(第17部門 マルチメディアストレージ1)

抄録

The optimum GPR target for Ba-ferrite tape systems was studied. The comparison among DC-free, DC-full, and DC-suppressed targets was made. Assuming GPRML detector with 16 or more Viterbi states, DC-free target generally showed the best bit error rate performance for both longitudinally and perpendicularly oriented media.
