N2 - Increase of the coercive force (Hc) and narrowing of the coercive force distribution (Δ Hc) was observed on double layered perpendicular rigid disks which were prepared by adding a small quantity of N2 during CoCr layer sputtering deposition. The effects of the N2 addition gave rise to an increase of output signal and D50. This change of recording property with N2 addition is due to narrow dispersion and reduction of CoCr grain diameter as measured by atomic force microscopy (AFM). But medium noise which was caused by magnetic inhomogeneity was also enhanced. Furthermore expansion of the domain size was found at the de-erased state by magnetic force microscopy (MFM).
