Abstract
A tape has a component of magnetization pointing out of a plane of the tape. To write a pulse of a servo pattern to the tape, the tape is passed over a write head with a conventional write gap. Current having a fixed polarity is provided to the write head. Once the current achieves a desired value, the current is no longer provided to the write head.
