Abstract
Micromagnetic modeling is utilized to study the track edge overwrite characteristics and correlations with grain easy axes orientation in longitudinal thin film recording media. The authors compare well-oriented films with planar isotropic films. It is found that for well-oriented films, the side-written band contains signal-related magnetic pole density. The pole density patterns exhibit strong dependence on previously written transitions at track edges. For planar isotropic media, edge overwrite simulation shows a clear side erase band. Read-back voltage waveforms are analyzed. A planar isotropic film shows much better off-track properties than an oriented film.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
