The present invention provides a magnetic recording medium having a thinned film back coating layer as well as suppressed tribocharging by sliding to the tape guide pin on running, and having excellent running durability. The present invention also provides a magnetic recording/reproducing system using the magnetic recording medium above. A magnetic recording medium 1 which comprises at least a magnetic layer 3 and a protective layer 4 comprising a hard film containing carbon as a principal component in this order on one surface of a non-magnetic support 2 , and comprises a metal layer 7 from 1 to 50 nm in thickness and a back coating layer 6 comprising a hard film containing carbon as a principal component in this order on the other surface of said non-magnetic support 2 . A magnetic recording/reproducing system, for recording and reproducing a tape-like magnetic recording medium above, by using a magnetic recording/reproducing device having a member on which said hard film containing carbon as a principal component is formed at parts in contact with a surface of said back coating layer. |
