Abstract:
1. A magnetic tape cartridge, comprising: a magnetic tape, said magnetic tape having servo information comprising: a plurality of parallel longitudinal servo bands that lie between a plurality of longitudinal data bands; said plurality of servo bands comprise odd servo bands and even servo bands, wherein each of said odd servo bands lie between said each of said even servo bands; each of said plurality servo bands comprising a plurality of frames, wherein each frame comprises a plurality of bursts of transition stripes, each burst having a first transition stripe; said first transition stripe of each burst of each said odd servo band is longitudinally shifted from said first transition stripe of each burst of each said even servo band by a substantially equal distance, D, such that said servo information of said odd servo bands is interleaved with said servo information from said even servo bands; and wherein said odd servo hands provide servo information at a first time and said even servo bands provide servo information at a second time such that a servo sampling rate is doubled, wherein said frame further comprises a first burst of transition stripes in a first azimuthal orientation and a second burst of transition stripes in a second azimuthal orientation different than said first azimuthal orientation, followed by a third burst of transition stripes in said first azimuthal orientation and a fourth burst of transition stripes in said second azimuthal orientation and wherein a distance between said first transition stripe of said first burst and said first transition stripe of said third burst is a distance B, wherein said magnetic tape is configured for a tape drive having a plurality of servo read elements, said first transition stripe of each burst of each said odd servo band is longitudinally shifted from said first transition stripe of each burst of each said even servo band by said substantially equal distance, D, wherein and wherein X is a number servo read elements of said tape drive.
