Abstract
The amount of displacement of a track recorded on a magnetic tape from the linear state is analyzed by using an image analysis apparatus, and a two-dimensional distribution state of the displacement state is displayed, so that a difference in the displacement state due to the position on the magnetic tape can be known, while the changes in the longitudinal direction of the magnetic tape or the variation state of the displacement in the time course can be obtained.
