ABSTRACT:
A clockwise helical groove is formed on the outer periphery surface of a rigid roller toward one end from the center position in the axial direction. A counter-clockwise helical groove is formed on the outer periphery surface of the roller toward the other end from the center position in the axial direction. The roller rotates, accompanied by a magnetic tape. The clockwise groove of the roller gives a regulating force, which points toward the center position, to the magnetic tape. The counter-clockwise groove of the roller gives a second regulating force, which points toward the center position, to the magnetic tape. The magnetic tape is given the regulating forces simultaneously that point toward the center position in the axial direction of the roller. The magnetic tape is restrained from swinging to one end or the other end in the axial direction of the roller, and the tape traveling becomes stable.
