Abstract

A tape storage medium comprises at least one servo band along a longitudinal extension of the tape storage medium for comprising positional information. The servo band comprises a first servo subband and a second servo subband extending along the longitudinal extension of the tape storage medium. The first servo subband comprises a frame servo pattern containing a first set of servo frames, wherein each servo frame of the set comprises a first burst and a second burst. Each burst comprises at least two servo stripes inclined at an angle with respect to a direction orthogonal to the longitudinal extension of the tape medium. The second servo subband contains a set of servo tracks extending along the longitudinal extension of the tape storage medium and arranged next to each other, wherein each servo track of the set contains a servo pattern of magnetic transitions.

Dependent claims

A tape storage medium comprising:

a tape storage medium comprising at least one servo band along a longitudinal extension of the tape storage medium, wherein the at least one servo band comprises positional information, and wherein the servo band further comprises:
a first servo subband extending along the longitudinal extension of the tape storage medium, the first servo subband comprising:
a first frame servo pattern containing a first set of servo frames, wherein each servo frame of the set comprises:
a first burst comprising at least one servo stripe inclined at a first angle with respect to a direction orthogonal to the longitudinal extension of the tape storage medium;
and
a second burst comprising at least one servo stripe inclined at a second angle with respect to the direction orthogonal to the longitudinal extension of the tape storage medium, the second angle being different from the first angle;
a second servo subband extending along the longitudinal extension of the tape storage medium next to the first servo subband, the second servo subband comprising:
a set of servo tracks extending along the longitudinal extension of the tape storage medium and arranged next to each other;
wherein each servo track of the set contains a servo pattern representing a waveform when being read;
and
wherein the waveforms of adjacent servo tracks are orthogonal to each other.
