Abstract:
A method and a system are provided for writing a plurality of servo bands on magnetic tape. The magnetic tape is moved longitudinally relative to at least one servo write head. The servo write head is positioned to write a plurality of parallel longitudinal servo bands. The plurality of servo bands comprise odd servo bands and even servo bands, and each of the odd servo bands lie between the each of the even servo bands. The at least one servo write head is operated to write the plurality of parallel longitudinal servo bands on the magnetic tape such that each of the plurality of servo bands comprise a plurality of frames, wherein each frame comprises a plurality of bursts of transition stripes, and each burst has a first transition stripe. The first transition stripe of each burst of each the odd servo band is longitudinally shifted from the first transition stripe of each burst of each even servo band by a substantially equal distance, D, such that servo information of the odd servo bands is interleaved with the servo information from the even servo bands.
