1. A data storage product, comprising:
a magnetic recording tape having written thereon at least two servo tracks extending along a longitudinal axis of the tape,
each servo track having a timing-based servo (TBS) pattern comprising a series of servo frames arranged to enable lateral positioning of a magnetic head relative to the servo tracks as well as tape dimensional stability (TDS) compensation via head skew,
each frame comprising a sequence of pairs of leading and trailing servo stripes,
wherein midpoints between the servo stripes in each pair, at all points having a same relative lateral height on the tape, are located along a virtual median line oriented at an angle β from perpendicular to the longitudinal axis of the tape, the angle β being greater than 1 degree.
