摘要：
The present invention provides a method for testing a disc shaped mold structure having a convexo-concave pattern formed on a surface thereof based on a desired design pattern, including at least: transferring a magnetic signal corresponding to a convexo-concave pattern formed on the entire surface of the mold structure to a medium in a direction perpendicular to the surface of the medium, obtaining a reproduction signal by electrically reproducing the magnetic signal from the medium onto which the magnetic signal has been transferred, and comparing the desired design pattern with the reproduction signal.
