Abstract
In this paper, the trench media can produce significant playback signals, since the maximum trench depth is comparable to the bit size a lithographic minimum feature size requirement. By DC magnetizing the trenches, their signal is a repeatable signal polarity pulse (bit writing must not switch the trench media).
