    • A magneto-optical disk which has a circular disk form and comprises a substrate provided with information pits and a guide groove, a recording medium layer provided on the substrate, and a protective layer formed of at least one thin film on the medium layer, in which the surface of the protective layer is minutely roughened to have a concave rough pattern and not to substantially protrude beyond a reference level composed of the outermost surface portions of the protective layer. When the magneto-optical disk is subjected to recording by a CSS system using an air floating magnetic head conforming to high-frequency recording in a magnetic field modulation type recording, which is one of methods of overwrite recording on magneto-optical disks, the minute concave rough pattern formed on the surface of the disk substrate prevents such troubles as adhesion of the magnetic head to the surface of the disk and collision between the disk substrate being rotated and the head.
    • 一种具有圆盘形状并包括设置有信息凹坑的衬底和引导槽的磁光盘,设置在衬底上的记录介质层和由介质层上的至少一层薄膜形成的保护层, 其保护层的表面被微小地粗糙化以具有凹形粗糙图案,并且基本上不突出超过由保护层的最外表面部分组成的基准水平。 当磁光盘通过使用在磁光调制型记录中的符合高频记录的空气浮动磁头的CSS系统进行记录时,其是在磁光盘上重写记录的方法之一,分钟 形成在盘基板表面上的凹形粗糙图案防止了磁头粘附到盘表面和盘基片旋转与头部之间的碰撞等问题。
