The playback screen will appear. Therefore, conventionally, a sample S obtained by cutting the video magnetic tape T in the vicinity including the pushing mark in the length direction is cut, and the surface shape is measured and inspected to find out how large (depth) the shape defect is. Up to this point, measurement is performed to determine whether or not the defective reproduction screen as described above falls within the allowable range. FIG. 1C shows a sample S having the shape defect P.
