Information storage and processing
 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.
