Abstract
An optical disk has a management area and a data area. In the data area, main picture information, sub-picture information used to construct streams in different languages, and audio information have been recorded. In the management area, attribute information used to identify each piece of sub-picture information on the streams has been recorded. The attribute information includes language code indicating kinds of language. The language code is supplemented with a code extension indicating differences in the size of characters and/or description obtained from the sub-picture information.
