摘要： A tape storage medium includes a tape head for reading/writing data from/to a tape storage medium. At least one servo band along a longitudinal extension of the tape storage medium determines positional information. The servo band includes a set of servo tracks having a width extending along the longitudinal extension and arranged next to each other. A total of two different servo patterns are contained in the set of servo tracks. The tape head includes two servo readers. A width of each servo reader orthogonal to the longitudinal extension of the tape storage medium is at least half the width of a servo track. The two servo readers are offset from each other orthogonal to the longitudinal extension by d*wST+n*wST with wST being the width of the servo track, with 0
