Abstract

A magnetic tape storage medium includes at least one servo band with at least two sub-bands along a longitudinal extension of the medium. Servo bursts are written to the sub-bands to determine positional information of the medium. A first of the sub-bands includes a first burst with at least one servo stripe inclined at a first non-zero angle with respect to a direction orthogonal to the longitudinal extension of the medium followed by a second burst comprising at least one servo stripe inclined at a second non-zero angle with respect to the direction orthogonal to the longitudinal extension of the medium, which second angle is different from the first angle. A second of the sub-bands includes a first burst having at least one servo stripe followed by a second burst having at least one servo stripe, the first and the second bursts parallel to each other.

Dependent claims

A magnetic tape storage medium, comprising:

at least one servo band with at least two sub-bands along a longitudinal extension of the tape storage medium;
servo bursts written to the at least two sub-bands for supporting to determine positional information of the tape storage medium;
wherein, in a first of the at least two sub-bands, a first burst comprises at least one servo stripe inclined at a first non-zero angle with respect to a direction orthogonal to the longitudinal extension of the tape storage medium, followed by a second burst comprising at least one servo stripe inclined at a second non-zero angle with respect to the direction orthogonal to the longitudinal extension of the tape storage medium, which second angle is different from the first angle;
wherein, in a second of the at least two sub-bands, a first burst comprises at least one servo stripe followed by a second burst comprising at least one servo stripe, which stripes of the first and the second burst are parallel to each other.
