Abstract
A rotating drum assembly, and a magnetic recording/reproducing apparatus including the rotating drum assembly, are provided. The rotating drum assembly comprises a cylindrical rotating drum; a magneto-resistive head installed on the rotating drum to project at least a part thereof from the outer surface of the rotating drum; and a tape-contact piece installed on the rotating drum so as to project from the outer surface of the rotating drum and to be in contact with the surface of a magnetic tape; the tape-contact piece being formed to have a larger tape-contact width than that of the magneto-resistive head and disposed to be in earlier contact with the magnetic tape than the magneto-resistive head.
