Abstract

An apparatus for analyzing tracking errors in magnetic tape holds a magnetic tape in a condition useful for examining the magnetic tape to measure the configuration of recorded tracks on the recording surface of the tape. The apparatus includes means for applying and maintaining a selected tension to the longitudinal and cross-web axes of the tape, a planar measuring surface having X and Y measuring scales allowing for measurement of distances between selected points on the recording surface of the tape, and a microscope or other sensing device for examining the recording surface
