Abstract
A method according to one embodiment comprises determining a growth rate of an erase band width between an aggressor track and a substantially unerased portion of a data track on a magnetic medium during a first number of write cycles on the aggressor track; and estimating the erase band width, or derived parameter thereof, for or after a second number of write cycles on the aggressor track, the second number of write cycles being greater than the first number of write cycles.
