Paper Abstract

To realize high density magneto-optical recording, it is important to suppress the disk noise. As we have reported, UV irradiation before sputtering films on the substrate could suppress the disk noise. But UV irradiation changed the shape of land and groove. We found that it caused poor recording power tolerance, because cross-talk could not be canceled using the phase compensation method. We developed a substrate formed by using a RIE process. Using this RIE-formed substrate, we could suppress the disk noise without UV-irradiation and improve the recording power tolerance.
