Abstract
By utilizing a micro-magnetic simulation model, the track edge noise is ana lyzed versus the head-media spacing in two different media. This study show s that although the track edge noise decreases with the head-media spacing within a normal range (27-69 nm), there is an unexpected slight increase in the track edge noise for lowering head-media spacing in the proximity and contact recording range around 6 nm, which brings a significant influence o n the contact recording performance with a narrow track.
