Abstract
A write head is provided for writing a servo pattern to a magnetic tape storage medium. The write head comprises at least a first write gap (A) and a second write gap (B), the first write gap (A) and the second write gap (B) being separately energizable. The second write gap (B) comprises at least a first section (a) and a second section (b). The first section (a) is designed such that an energization of the second write gap (B) causes a magnetic flux across the first section (a) insufficient for changing a magnetization of a track of the magnetic tape storage medium (TP) passing the first section (a) of the second write gap (B). The second section (b) is designed such that an energization of the second write gap (B) causes a magnetic flux across the second section (b) sufficient for magnetizing a track of the magnetic tape storage medium (TP) passing the second section (b) of the second write gap (B).
