Abstract
The concept is advanced that the write head current amplitude which produces maximum output for a given set of recording conditions can be determined by three nearly independent factors. The first is a static factor related to the head geometry and reluctance at very low frequencies. The second is a time factor related to the tape speed and transient response of the head and the third, a density factor, is determined by the recorded bit density. The time and density factors can be expressed by a set of normalized curves which are relatively independent of head characteristics.Keywords
