We use the Fourier Transform Grid Method as the basis for a new approach to analyzing the displacement distribution of the track on which signals are recorded in magnetic recording systems. It is important to make the track width narrower for high density recording on magnetic tape. However, as the track becomes narrower, track linearity must be improved. To improve track linearity, it is necessary to clarify the displacement distribution of the track accurately. Our new measuring method can obtain a two-dimensional distribution of the displacement accurately and can clarify the relation between the displacement distribution and the factors that deteriorate track linearity.
