Tape storage system

A method for operating a tape storage system, the method comprising:

• reading a servo band by two servo readers configured to read from the servo band;
• and
• determining a lateral position value of a tape head containing the servo readers relative to a tape storage medium from a readback signal of the servo readers and adjusting a lateral position of the tape head dependent on the lateral position value;
• wherein the tape storage system comprises:
• the tape head configured to read and/or write data from and/or to the tape storage medium;
• the tape storage medium comprising the servo band along a longitudinal extension of the tape storage medium to determine positional information;
• the servo band comprising a set of servo tracks having a width extending along the longitudinal extension of the tape storage medium and arranged next to each other;
• each servo track of the set containing a servo pattern;
• a total of two different servo patterns contained in the set of servo tracks;
• the servo patterns of adjacent servo tracks being different from each other;
• the tape head comprising the two servo readers configured to read from the servo band;
• 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;
• and
• the two servo readers offset from each other orthogonal to the longitudinal extension of the tape storage medium by d*wST+n*wST, wherein wST is the width of the servo track, with 0<d<1, and with n being an integer n=[0, 1, 2 . . . , N] where N corresponds to the number of servo tracks in the set.

A computer program product comprising a non-transitory, computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising instructions that, when executed by a computer perform a method for operating a tape storage system, the method comprising:

• reading a servo band by two servo readers configured to read from the servo band;
• and
• determining a lateral position value of a tape head containing the servo readers relative to a tape storage medium from a readback signal of the servo readers and adjusting a lateral position of the tape head dependent on the lateral position value;
• wherein the tape storage system comprises:
• the tape head configured to read and/or write data from and/or to the tape storage medium;
• the tape storage medium comprising the servo band along a longitudinal extension of the tape storage medium to determine positional information;
• the servo band comprising a set of servo tracks having a width extending along the longitudinal extension of the tape storage medium and arranged next to each other;
• each servo track of the set containing a servo pattern;
• a total of two different servo patterns contained in the set of servo tracks;
• the servo patterns of adjacent servo tracks being different from each other;
• the tape head comprising the two servo readers configured to read from the servo band;
• 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;
• and
• the two servo readers offset from each other orthogonal to the longitudinal extension of the tape storage medium by d*wST+n*wST, wherein wST is the width of the servo track, with 0<d<1, and with n being an integer n=[0, 1, 2 . . . , N] where N corresponds to the number of servo tracks in the set.
