Magnetic tape storage medium

A method for writing a servo pattern to a magnetic tape storage medium, the method comprising:

• moving a magnetic tape storage medium and a servo band across first and second gaps of a write head module in a direction along the longitudinal extension of the magnetic tape storage medium;
• applying a current pulse to a coil of the write head module;
• continuing to move the magnetic tape storage medium;
• and
• applying another current pulse to the coil;
• wherein the magnetic tape storage medium comprises at least one servo band with at least two sub-bands along a longitudinal extension of the tape storage medium, and servo bursts written to the at least two sub-bands for supporting to determine positional information of the tape storage medium, wherein, in a first of the at least two sub-bands, a first burst comprises at least one servo stripe inclined at a first non-zero angle with respect to a direction orthogonal to the longitudinal extension of the tape storage medium, followed by a second burst comprising at least one servo stripe inclined at a second non-zero angle with respect to the direction orthogonal to the longitudinal extension of the tape storage medium, which second angle is different from the first angle, and wherein, in a second of the at least two sub-bands, a first burst comprises at least one servo stripe followed by a second burst comprising at least one servo stripe, which stripes of the first and the second burst are parallel to each other;
• and
• wherein the write head module comprises at least one coil configured to generate a magnetic flux when applying an electric current to the coil;
• and
• a pole piece structure configured to guide the generated magnetic flux, wherein the pole piece structure comprises:
• a first section configured to write a servo pattern to the first sub-band of a servo band of the tape storage medium, the first section comprising a first gap in the form of a stripe inclined at a first non-zero angle with respect to a direction orthogonal to a longitudinal extension of the tape storage medium when being written, and a second gap in the form of a stripe inclined at a second non-zero angle with respect to a direction orthogonal to a longitudinal extension of the tape storage medium when being written, which second angle is different from the first angle;
• and
• a second section next to the first section for writing a servo pattern to a second sub-band of the servo band of the tape storage medium, the second section comprising a first gap in the form of a stripe, and a second gap in the form of a stripe, which first and second gap are parallel to each other.
