Abstract :
The characteristics of advanced write- and nonequalized tape channels have been modeled and evaluated to investigate the impact of the equalization on future tape channels, realizing that several factors regarding write-equalization (WE) should be taken into account. It is found that the use of WE can improve nonlinear distortion in the write process and reduce read-equalizer requirements even for media with a moment (MRδ) as low as 1 memu/cm2, and may therefore continue to offer advantages to future thin metal-particle tape systems
