Abstract
A new parameter ΔHc on M-H minor curves is introduced to estimate the standard deviation of the Hk distribution. The ΔHc correlates strongly to coercivity squareness s* and half-width of switching field distribution SFD. and needs no compensating for the demagnetizing field in perpendicular recording media. It was shown by computer simulation analysis that the magnetic recording performance depends greatly upon the particle's anisotropy field Hk distribution in recording media as well as coercivity and saturation magnetization. The narrow Hk distribution of Co-Cr sputtered media is derived from the high crystallinity, and leads to superior performance in high density recording.
