A small quantity nitrogen was added to CoCr thin film during sputtering deposition in order to reduce the inter- granular magnetic interaction. This addition increased the CoCr coercive force (Hc)and reduced the Hc dispersion in CoCr grains. Consequently, the reproduced output and D50 were improved. On the other hand, the media noise caused by magnetic inhomogeneity was also enhanced. This change in the magnetic property is due to the effect of disturbance of the CoCr grain growth by nitrogen addition.
