A structure and method are described that make it possible to store both open-format data and closed-format data on a single storage medium, such as a DVD disc, by organizing the data in an open file data system and a specialized closed file data system. The closed file data system may be encapsulated in the open file data system The storage medium is segmented into open file data spaces, containing data recorded using the open-format techniques, and closed file data spaces, containing data recorded using closed-format techniques, or using a specialized technique. The open-format data can be accessed using both open-format and close-format hardware, whereas the closed-format data can only be accessed using specialized hardware.
