MAGNETO-OPTICAL DISK AND METHOD OF MANUFACTURING THE SAME

摘要

A magneto-optical disk has a substrate whereon a recording medium is formed, and a depression is formed on the substrate on the inside of the recording medium of the substrate. A center hub is installed on the depression such that the center hub is substantially level with a protective- resin layer covering the recording medium. On the center hub, a flying head performs CSS (Contact-Start-and-Stop). This configuration of the disk eliminates the occurrence of dust due to abrasion and head crash, and achieves stable CSS. A method of manufacturing the magneto-optical disk is also disclosed, wherein the protective-resin layer is formed after installing the center hub on the depression. In this method, since a space is not produced between the center hub and the protective-resin layer, stable flying characteristics are obtained. And a magneto-optical disk is disclosed, whereon small physical bumps and pits are formed on the substrate on the inside of the recording medium, which prevents the flying head from sticking to the disk. A method of manufacturing the magneto-optical disk by using a stamper, which permits the disk to be mass-produced, is also disclosed.
