Abstract:
1. A magnetic tape medium, comprising: at least one servo band along a longitudinal extension of the tape medium, the at least one servo band comprising servo patterns organized in servo frames for supporting to determine positional information; at least one of the servo frames comprising a first burst comprising at least two servo stripes inclined at a first angle with respect to a direction orthogonal to the longitudinal extension of the tape medium, followed by a second burst comprising at least two servo stripes inclined at a second angle with respect to the direction orthogonal to the longitudinal extension of the tape medium, which second angle is different from the first angle; and wherein at least one of the stripes of the first burst has a first magnetic polarity, and wherein at least one of the stripes of the second burst has a second magnetic polarity different from the first magnetic polarity; and wherein, for at least one of the first and second bursts, different stripes within a same burst have opposite magnetic polarities with respect to one another.
