Abstract
In a servo writer, a write signal generator circuit is configured to output a signal for writing a servo signal to a servo write head disposed to allow a magnetic tape to slidably contact therewith and configured to write the servo signal thereon, and a plurality of tape guides are configured to guide the magnetic tape supplied from a supply reel to the servo write head and to a take-up reel. The plurality of tape guides include a first tape guide disposed to contact with the magnetic tape at a position directly upstream of the servo write head and a second tape guide disposed to contact with the magnetic tape at a position directly downstream of the servo write head. Each of the first and second tape guides includes a guide roller rotatably supported by an air bearing and having a diameter of 19 mm or greater.
