Abstract
A servo track write head writes low frequency transitions for fine transverse positioning and high frequency fields providing additional information. The servo track write head includes a first write gap with at least one gap section at a first angle relative to a tape direction. A second write gap has at least one gap section at a second angle, not equal to the first angle. The first and second write gaps write low frequency transitions in each servo frame. A third write gap writes high frequency transitions in each servo frame.
