Abstract

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