A guide roller mounted in a tape drive for reducing mechanical noise associated with travel of a magnetic tape medium in a tape path is provided. The guide roller includes a cylindrical barrel, which is rotatably coupled to a tape drive. The cylindrical barrel rotates as the magnetic tape medium is guided by the guide roller as it travels through the tape path. A continuous helical groove forms a spiral on the outer surface of the cylindrical barrel along the length of the cylindrical barrel. The continuous helical groove forms contiguous rings of the spiral.
