Phase‐change‐type erasable optical recording media can be overwritten in a simple process, which should lead to a faster data transfer rate and cheaper optical storage devices. The properties of various protective layer materials for optical disks have been investigated, including their surface flatness (see Figure), reflectivity stability and error modes during repeated overwriting.
