    Micromagnetic simulations have been performed to compare the recording performance of oriented media (M[sub r]=1.50) with planar isotropic media in longitudinal recording.

    Magnetic patterns were created by locally altering the magnetic coercivity of a perpendicular anisotropy film by ion irradiation. The resulting pattern, after dc magnetizing, consists of regions having alternating up/down magnetization patterns in remanence. In this case, the magnetization of...
