Abstract

Data and directories are separated and stored on separate parts of an optical disk. Data and directories are written from magnetic disk storage in a first specific format that is determined by a particular operating system used by an information processor. Directories are on the inner tracks and data are on the outer tracks, in a second format on the optical disk. A medical information processing system is provided with an external magnetic disk storage and the optical disk.
