<p>A magnetic recording medium has a support provided with at least on one side of the support a magnetic layer having at least a granular structure, and a protective layer in this order, wherein the protective layer is a hard carbon film formed by an ion beam deposition process, and the protective layer has a ratio of a strength of G peak (IG) having a peak in a range of from 1,500 to 1,600 cm<-1> in Raman spectrum according to Raman spectroanalysis and a strength of D peak (ID) having a peak in a range of from 1,350 to 1,430 cm<-1>, (ID/IG), of from 0.5 to 1.0.</p> |
