FEED-FORWARD DC RESTORATION IN A PERPENDICULAR MAGNETIC READ CHANNEL |
摘要 |
<p>A method of feed-forward DC restoration in a perpendicular magnetic read channel is disclosed. The method generally includes the steps of (A) generating a feed-forward signal by performing a first detection on an input signal, wherein a DC component of the input signal was previously filtered out in the perpendicular magnetic read channel, (B) generating a restored signal by summing the input signal and the feed-forward signal, the summing restoring the DC component previously filtered out and (C) generating an output signal by performing a second detection on the restored signal, wherein the first detection is independent of the second detection.</p> |
