Magnetic tape medium with magnetically encoded servo band bursts

摘要

A magnetic tape medium includes at least one servo band along a longitudinal extension of the tape medium which at least one servo band comprises servo patterns organized in servo frames for supporting to determine positional information. At least one of the servo frames includes a first burst comprising at least two servo stripes inclined at a first angle with respect to a direction orthogonal to the longitudinal extension of the tape medium, followed by a second burst including at least two servo stripes inclined at a second angle with respect to a direction orthogonal to the longitudinal extension of the tape medium, which second angle is different from the first angle. At least one of the stripes of the first burst has a first magnetic polarity and at least one of the stripes of the second burst has a second magnetic polarity different from the first magnetic polarity.

1. A magnetic tape medium, comprising:
at least one servo band along a longitudinal extension of the tape medium, the at least one servo band comprising servo patterns organized in servo frames for supporting to determine positional information; at least one of the servo frames comprising a first burst comprising at least two servo stripes inclined at a first angle with respect to a direction orthogonal to the longitudinal extension of the tape medium, followed by a second burst comprising at least two servo stripes inclined at a second angle with respect to the direction orthogonal to the longitudinal extension of the tape medium, which second angle is different from the first angle; and wherein at least one of the stripes of the first burst has a first magnetic polarity, and wherein at least one of the stripes of the second burst has a second magnetic polarity different from the first magnetic polarity; and wherein, for at least one of the first and second bursts, different stripes within a same burst have opposite magnetic polarities with respect to one another.
