    摘要： 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.

    摘要： A tape storage medium comprises at least one servo band (SB) along a longitudinal extension (x) of the tape storage medium (TP) for supporting to determine positional information. The servo band (SB) comprises a set of servo tracks (STx) extending along the longitudinal extension (x) of the tape storage medium (TP) and arranged next to each other. Each servo track (STx) of the set contains a servo pattern with magnetic transitions at a defined frequency (fx), wherein the frequencies (fx) of magnetic transitions of servo patterns of adjacent servo tracks (STx) are different from each other. The set of servo tracks (STx) contains at least three servo tracks (STx) with magnetic transitions of different frequencies (fx).

    摘要： In a method for operating a tape storage system, readback signals are simultaneously received from a set of data readers reading from data tracks of a set of adjacent data tracks extending along a longitudinal extension of a tape storage medium, wherein each data track of the set has a width and each data reader of the set has a width equal to or less than the width of a data track. Simultaneously to receiving the readback signals from the set of data readers readback signals are received from a servo reader arrangement containing at least one servo reader arranged laterally offset from one of the data readers by less than the width of a data track. At least one of lateral position, velocity, gain and timing information is determined dependent on the readback signals of each servo reader in the servo reader arrangement.
