Abstract
A tape storage medium comprises at least one servo band (SB) along a longitudinal extension (x) of the tape storage medium (TP) for supporting to determine positional information. The servo band (SB) comprises a set of servo tracks (STx) extending along the longitudinal extension (x) of the tape storage medium (TP) and arranged next to each other. Each servo track (STx) of the set contains a servo pattern with magnetic transitions at a defined frequency (fx), wherein the frequencies (fx) of magnetic transitions of servo patterns of adjacent servo tracks (STx) are different from each other. The set of servo tracks (STx) contains at least three servo tracks (STx) with magnetic transitions of different frequencies (fx).
