Write equalization in future tape channels

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-equal ization (WE) should be taken into account, It is found that the use of WE c an improve nonlinear distortion in the write process and reduce read-equali zer requirements even for media with a moment (M(R)delta) as low as 1 memu/ cm(2), and may therefore continue to offer advantages to future thin metal- particle (MP) tape systems.
