Servo pattern of a tape storage medium
WO 2014083508 A3
Abstract
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 first servo subband (SB1) extending along the longitudinal extension (x) of the tape storage medium (1) and a second servo subband (SB2) extending along the longitudinal extension (x) of the tape storage medium (TP) next to the first servo subband (SB1). The first servo subband (SB1) comprises a frame servo pattern containing a set of servo frames (FR), wherein each servo frame (FR) of the set comprises a first burst (A) comprising at least two servo stripes (SP1) inclined at a first angle ( α) with respect to a direction orthogonal to the longitudinal extension (x) of the tape medium (TP), followed by a second burst (B) comprising at least two servo stripes (SP2) inclined at a second angle (β) with respect to the direction orthogonal to the longitudinal extension (x) of the tape medium (TP), which second angle (α) is different from the first angle (β). The second servo subband (SB2) contains a set of servo tracks (STx) extending along the longitudinal extension (x) of the tape storage medium (TP) and arranged next to each other, wherein each servo track (STx) of the set contains a servo pattern of magnetic transitions representing a waveform when being read, and wherein the waveforms of adjacent servo tracks (STx) are orthogonal to each other.
