A recording at a channel rate of 200 Mbps in helical tape systems

Summary form only given. We have reported a helical-scan tape system using MR heads as read heads. In this work, we have studied a tape recording at a channel rate of 200 Mbps, which is about double that of the current recording tape-streamer. By using MR heads and low noise ME tape, we have improved the performance of the CNR of the high clock-rate read channel. The impedance noise spectrum of the MR head is flat. The media noise is dominant in the total noise. The power of the media noise is kept constant at various recording rate.
