Abstract
A method for writing a servo pattern to a magnetic tape medium by a write head is described. The write head includes a coil configured to generate a magnetic flux when applying an electric current thereto, and a pole piece structure configured to guide the generated magnetic flux. The method includes moving the magnetic tape medium with its servo band above the two gaps in a direction along the longitudinal extension of the magnetic tape medium, applying a current pulse to the coil, continuing to move the magnetic tape medium, and applying another current pulse to the coil. The magnetic tape medium includes at least one servo band along the longitudinal extension of the tape medium having servo patterns organized in servo frames for supporting to determine positional information.
