Abstract
Experimental, analytical, and numerical methods are used to describe the behavior of axially moving magnetic tape. In-plane transverse vibrations are measured using various measurement methods, and in various environments. In particular, measurements are made to ascertain the lateral vibrations of tape above 500 Hz (high frequency lateral tape motion). The sources of lateral vibration of tape are investigated, categorized, and rated according to their contribution to the overall vibration amplitude. Position error signal and the track misregistration (TMR) budget are defined and discussed within the context of tape recording technology and their relationship to lateral tape motion. Tape transport elements are investigated and evaluated based on their performance with respect to lateral tape motion measurements. An analytical model is used to predict the tape displacement from one transport element to the next. A numerical simulation is developed for a tape moving on a transport, and results are compared to experimental measurements.
