摘要
A servo writer includes a writing head that writes a servo signal on a long magnetic tape that is traveling and at least two first guide rollers that guide the travel of the magnetic tape, in which the at least two first guide rollers on which a spiral groove is provided have a circumferential surface that has contact with the traveling magnetic tape, tensile forces act on the magnetic tape from the at least two first guide rollers in a width direction of the traveling magnetic tape, and the tensile forces that act on the magnetic tape from the at least two first guide rollers cancel each other.
