Abstract
Lateral motion of magnetic tape is measured on roller and porous air-bearing type tape drives. The lateral tape motion signal is high-pass filtered and the spectral components are analyzed. Time-frequency analysis is also performed. The effect of lateral motion of tape on tape pack winding is investigated and the frequencies observed during edge contact are analyzed. The effect of dynamic tension changes during high frequency lateral motion events is examined, and the tension difference across a section of tape is found to be correlated to the lateral motion of that section. LDV data of out-of-plane (transverse) tape motion is presented and its relationship to lateral tape motion and edge contact is discussed.
