Abstract
We developed a DyFeCo magneto-optical disk using a protective film made of Ce-SiO2. The disk structure, composition, and sample preparation conditions were optimized to provide adequate read-write characteristics and reliability. Since DyFeCo is considerably less expensive than TbFeCo, our disks are practical alternative.Keywords
