              1.  A magnetic recording medium which comprises at least a                            
              magnetic layer and a protective layer comprising a hard                               
              film containing carbon as a principal component in this                               
              order on one surface of a non-magnetic support, and                                   
              comprises a back coating layer comprising a hard film                                 
              containing carbon as a principal component on the other                               
              surface of said non-magnetic support, wherein a surface of

              surface roughness SRa in a range of 3 to 7 nm and a three-                            
              dimension ten-point average roughness SRz in a range of 30                            
              to 55 nm.
