Recent advancement of recording technologies provides us higher density, huge capacity memory devices, such as digital video disks and magneto-optical disks. The higher density is realized for making the recording marks smaller. The size of the recording marks became smaller in the DVD media. In the development of these media, direct observation of the recording marks is important, because the memory performance strongly depends on the shape or the size of them.
