ABSTRACT:
Disclosed is a servo writer in which a servo write head is easy to exchange, and which writes, to magnetic tapes, a servo signal from which a reading signal of the improved SN ratio can be obtained. The servo writer includes a magnetic tape running system, at least one DC erase head, a plurality of servo write heads being arranged downstream of the DC erase head, and an installation section on which the servo write heads are arranged and which includes a switching mechanism for switching the servo write heads to position one of the servo write heads at a location possible to write the servo signals on the magnetic tape.
