Magnetic tape: A high performer: Magnetic tape has evolved into a highly effective medium for high-density and low-cost-per-bit data recording

Discusses the codes and conversion techniques that allow high-density recording of digital signals, and also explains some of the basic techniques involved in digital recording. And, since all of the more sophisticated uses of magnetic tape are based on a background of analog-signal recording, this article begins by taking a closer look at some of the fundamentals of that technology.
