Abstract :
Interactions and switching characteristics of thin-film recording media with varying degrees of out-of-plane anisotropy have been measured and correlated to media noise. Unlike conventional magnetic measurements that can relate to media noise for media having strong in-plane orientation, the technique utilized is shown to provide an improved method for quantifying interactions that correlate to media noise, even in the case of films with significant perpendicular anisotropy. CoPt12Cr13 films sputtered onto Cu or Cr underlayers are discussed
