摘要：
A system to observe the magnetic domain recorded on a magneto-optic disk with a multi-layer structure was suggested. The four parts, reading. writing, erasing and domain observation, are combined into a whole. By applying a digital image processing technique, the blurred domain image can be segmented and enhanced, and the domain morphology can be observed directly under various recording conditions. Additionally, the resolution and pixel spacing for the image system are discussed. In an experiment using this system we observed the domain on a direct overwrite disk and a non-direct overwrite disk, and analyzed the reasons for the difference. (C) 2000 Elsevier Science S.A.
